INTRODUCTORY UNITWHAT TECHNICAL ENGLISH IS ALL ABOUT:
ENGL ISH FOR SPECIFIC PURPOSES (ESP)
ESP is an approach to language teaching in which all the decisions as to content and
method are based on the learners reason for learning, thus, it is focused on the
learners needs and interests to influence on their motivation and therefore in the
effectiveness of their learning, and aims to meet the needs of particular learners, so
teachers have to design courses for various groups of learners. (Excerpted from
Hutchinson, T and A. Waters. (1993) English for Specific Purposes, Cambridge:Cambridge University Press)
GENERAL OBJECTIVES OF THE COURSETECHNICAL ENGLISH FOR MECHANICAL
ENGINEERING
1. To read materials written in the English Language in the field of Mechanical
Engineering
2. To value the importance of English as an instrument for accessing scientific
and technical information.

ENGLISH FOR SPECIFIC PURPOSES(ESP)vs.GENERAL ENGLISH
GENERAL ENGLISH ESP
-Elementary and high school English-Development of four skills ( listeningcomprehension, reading
comprehension, speaking and writing)-Conversational English Courses (ESL,EFL)
-Language of Science andTechnology-Language for OccupationalPurposes-Development of one skill: readingComprehension
READING COMPREHENSION vs. TRANSLATION
THE READING PROCESS THE TRANSLATIONPROCESS
-Reading is a communicative activity
where there is an active interaction
between the reader and a written text
(Widdowson, 1979).
-The reader perceives a written text in
order to understand its content. The
understanding that results is called
reading comprehension (Richards,
1985).
-Understanding a written text means
extracting the required information
from it as efficiently as possible
(Grellet, 1981).
-The process of changing speech or
writing from one language into
another.
-A translation which reproduces the
general meaning and intention of the
original but which does not closely
follow the grammar, style or
organization of it is known as a free
translation. A translation which
approximates to a word-for-word
representation of the original is known
as a literal translation (Richards,
1985).
MAIN READING STRATEGIES
SKIMMING Quickly running ones eyes over a text to getthe gist of it (Grellet, 1981).
SCANNING Quickly going through a text to find a
particular piece of information (Grellet, 1981).GUESSING An opinion reached by deducing (WebsterDictionary, 1981).
INTENSIVE READING Reading shorter texts, to extract specificinformation. This is more an accuracy activityinvolving reading for detail (Grellet, 1981).

READING STRATEGIES
How do you deal with an unknown word in a text?1._______________________________2. _______________________________3. _______________________________
There are several ways to approach unknown words we find when we are reading.
GUESSINGGUESSING THROUGH COGNATES
Cognates are words that have the same or similar spelling and the same
meaning in English and Spanish
Examples: mechanic, fluid, reactor, viscosity
Occasionally we may also find false cognates which are words that have thesame or similar spelling in English and Spanish, but their meaning is different inboth.
Examples: large, actual, actually
Practice. Underline the cognates you find in the following sentence.
The materials selected for the manufacturing of TUCAL ice machine are firstclass, and they are subjected to a rigorous reception exam in order toguarantee high efficiency and minimum maintenance.
GUESSING BASED ON BACKGROUND KNOWLEDGEEvery one of us has some general knowledge about the world in which we liveand that background knowledge can help us guess the meaning of an unknownword.
Example:A gas turbine is an engine that employs gas flow as the working medium bywhich heat energy is transformed into mechanical energy. Gas is produced inthe engine by the combustion of certain fuels

GUESSING BASED ON CONTEXT
Using context to understand unfamiliar wordsIf you are learning English as a second/foreignlanguage, meeting unfamiliar words is a regularexperience. With proper reading skills, this is not aproblem, but an excellent opportunity to rapidlyincrease your vocabulary. The most important skillfor this purpose is your ability to use context thewords and sentences which surround an unfamiliarword.
There are a number of different techniques forguessing an unfamiliar word's meaning fromcontext:
*. Read the sentence/passage and try to guess
the meaning of the highlighted word.
* Explain what part of the context surrounding the word allowed you to makeyour guess.
The context gives us lot of clues through which we can guess the meaning of anunknown word.
a. Definitions: A nuclear reactor which produces more fuel than it consumesis referred to as a breeder reactor.
b. Explanations: A four-cycle engine is an internal combustion engine inwhich the pistons complete four strokes__intake, compression,power and exhaust__for each complete cycle.
c. Examples: Propulsion is the action of propelling an object, e.g. a jetengine is used for the propulsion of an airplane.

d. Synonyms: Dope, any of various viscous materials used on pipe ortubing threads as a lubricant, is used to prevent corrosion.
e. Antonyms: The efficiency of gas-turbine cycles can be enhanced by theuse of auxiliary equipment such as intercoolers, regenerators andreheaters. These devices are expensive, however and economic
considerations usually preclude their use.
f. Related Words: The usual fuels used in gas turbines are natural gas andliquids such as kerosene and diesel oil. Coal can be used after conversionto gas in a separate gasifier.
GUESSING THROUGH WORD FORMATIONOne of the ways to guess the meaning of the unfamiliar words you come acrosswhen you read is to analyze the way words in English are generally formed. AnEnglish word can be divided in three parts: a prefix, a stem and a suffix.
Pre- means before, a prefix, therefore, is what comes before the stem. Consideras an example the prefix de- (meaning reduce or reverse) in a word likedemagnetize (meaning to deprive of magnetism). A suffix is what is attached tothe end of the stem. Consider as an example the suffix er (meaning theperson/thing who/that) inproducer (the person or thing that produces).Suffixes, on the other hand, change the word from one part of speech toanother. For example, -ly added to the adjective tremendous forms the adverbtremendously.
The following is a list of the most common suffixes in English corresponding todifferent categories:
NOUNS (*) VERBS (**) ADJECTIVES ADVERBS-ance -ize -able -ly-ence -fy -ible-or -en -less-er -ful-ist -al,ic,ical
-ness -ish-ity -ive-ion -ous-ite
-ment
(*) may be in plural (**) may take s/-es (3rd. person singular)

Practice. Read the following sentences and underline all the suffixes youfind.
1. For the production of ice blocks, water is frozen in an equipmentmanufactured with highly anticorrosive aluminium, employing a technology
related to the vertical plate freezers.
2. The gas turbine was installed with the major auxiliary systems in aspacious acoustic enclosure.
3. A displacement pump imparts energy by mechanical displacement.
4. The term standards has many implications. To the researcher and to thetechnical community it may mean fundamental test methodologies andunits of measure.
5. The meter is connected to the primary element in substantially the samemanner as is the conventional mercury manometer.

The words engine and "ingenious" are derived from the same Latin root,"ingenerate", which means "to create". The early English verb engine meant "tocontrive". Thus the early "engineers" were the people who contrived (i.e. invented)new things.
The history of mechanical engineering can be traced directly to the ancient world,to the designers and inventors of the first mechanisms which were powered by humanor animal labour, water or wind energy, or a combination of these.
Although many of the mechanisms had a purely peaceful application, such as forflight, irrigation or building, the word "engineer" originally meant "military engineer"because it was derived from the term "engines of war". These were machines such ascatapults, floating bridges and assault towers. The invention of the steam engine in thelatter part of the 18th century provided a key source of power for the IndustrialRevolution and gave enormous impetus to the development of machinery of all types.
As a result, a new major classification of engineering dealing with tools and machines,namely mechanical engineering, received formal recognition in 1847.
Today's mechanical engineer is heavily involved in the development and use of
new materials and technologies, especially in computer aided engineering. A rapidlygrowing field for mechanical engineers is environmental control, comprising thedevelopment of machines and processes that will produce fewer pollutants, as well asthe development of new equipment and techniques to reduce or remove existingpollution. Although mechanical engineers may occasionally work alone on a smallproject, they are more likely to be working on large, multi-disciplinary projects, liaisingwith specialists from other areas.
In almost every sphere of modern life, from the air-conditioned office or home to themodern industrial plant or mode of transport, one sees the work of mechanical
engineers who continue to develop and apply new knowledge and technology toimprove the quality of life for society as a whole.

Very often nouns form chains with one ore more words called modifiers. Thefunction of theses modifiers is to describe the noun in more detail.Noun modifiers can be premodifiers (a beautifulgirl) or postmodifiers (the girl in thered dress).
A noun may be modified by:
1) An adjective
Examples:
Mechanical tools, chemical reaction, hazardous condition, sharp edge, large vessel,careful driver
2) Another noun
InEnglish we can put two nouns together. The first noun is used as an adjective tomodify the second noun and is called a noun adjunct. The first noun is almostalways singular because it follows the rule for adjectives, which do not have pluralforms in English.
a. N1 is a kind ofN2 (a grammar book is a kind ofbook)b. N1 is an object of an implied verb (an ice machine is a machine thatmakes ice)
It is important to understand that N2 is the thing and N1 is the kind or type:a grammar book is a bookan ice machine is a machineN1 is singular, even if the phrase is plural.
My teacher showed me a grammar book in class.
In the office there is a new ice machine.
Examples:
Foundry process, flow meter, cost reduction, energy distribution, pressurevalve, exhaust pipe

tower, braking device
4) An -ed form
Examples:

Practice.a) Circle the modifiers of the underlined nouns
Before beginning a welding job, it is important to identify the hazards for that
particular welding operation. The hazards will depend on the type of welding, the
materials (base metals, surface coatings, electrodes) to be welded, and the
environmental conditions (outside or in a confined space, for instance).
Ask for material safety data sheets (MSDSs) to identify the hazardous materialsused in welding and cutting products, and the fumes that may be generated.
Eye protection should be used to protect the eyes from bright light, heat,
ultraviolet light, and flying sparks. For the best protection, wear face shields or
helmetsandgoggles. To keep particles out of your eyes when removing your face
shield, tip your head forward and keep your eyes closed.

b) Find examples of each noun chain in the sentences provided. Try to find morethan one example for the first two patterns.
Many industries are beginning to use robot welders in place of workers on the
assembly line. This removes workers from the hazard, but focuses on job
elimination rather than workplace improvements. In addition, a number of injuredworkers can result from careless operation of industrial welding robots.

Scottish veterinarian John Boyd Dunlop invented the first air-filled or pneumatic tires in
1888. He attached rubber hoses to wooden wheels and covered the contact patches with thick
canvas. The bead wire tire invented by C.K. Welch in 1891 marks an important breakthrough
in tire history. That same year, the Michelin brothers patented tires that could be mounted or
demounted by hand. In 1904, Firestone and Goodyear Tire Company developed straight sided
wire bead tires and almost all the tire manufacturers in the US were following their
manufacturing techniques by 1908.
Meanwhile in 1913, Britain developed the radial ply method (plies at right angles to the
sidewall) which broke from the previous bias ply method which used tire code fabric.
However, the radial ply method (crossed under the tread) only came into wide use some 35
years later, in 1948, when it was adopted by Michelin. The code fabric was made from a
weave of thick cotton thread. Due to high prices, the stronger silk thread could not be used in
manufacturin tire code fabric.

Disc Brake Basics
The main components of a disc brake are: The brake pads and the caliper,
which contains a piston and the rotor, which is mounted to the hub. The disc
brake is a lot like the brakes on a bicycle. Bicycle brakes have a caliper, which
squeezes the brake pads against the wheel. In a disc brake, the brake pads
squeeze the rotor instead of the wheel, and the force is transmitted
hydraulically instead of through a cable. Friction between the pads and the
disc slows the disc down.

How to Change Your Air Filter
1. Open the hood.2. Locate your air filter, usually found on top of the engine. On cars with
carburetors it is in a round piece of metal about the size of a mediumpizza; fuel-injected cars have square or rectangular air filter housingsthat may be off to the side of the engine.
3. Unscrew or unclamp the top to the air filter housing.4. Lift out the air filter. It should be a round or rectangular filter made of
paper or plastic, with a rubber rim.5. Clean the area with a vacuum cleaner or seal the top of the carburetor.
This will keep debris out of the carburetor as you continue to clean thehousing.
6. Clean out any dirt or bugs from the inside of the air filter housing with arag
7. Replace the filter with a new filter. Consult your manual to determine theproper filter for your car.
8. Replace the cover and close the hood.

Machine tools may be classified under three main categories: conventional
chip-making machine tools, presses, and unconventional machine tools.Conventional chip-making tools shape the workpiece by cutting away theunwanted portion in the form of chips. Presses employ a number of differentshaping processes, including shearing, pressing, or drawing (elongating).Unconventional machine tools employ light, electrical, chemical, and sonicenergy; superheated gases; and high-energy particle beams to shape theexotic materials and alloys that have been developed to meet the needs ofmodern technology (Machine Tools," Microsoft Encarta Encyclopedia 99. 1993-1998 Microsoft Corporation)
The refrigeration cycle
The pressure in the system drops as the water cools and absorbs ammoniavapor. Liquid ammonia flows into the evaporator, begins to evaporate, andcools it. Evaporated ammonia flows back through the tube. It is againabsorbed by the water in the generator. Refrigeration continues, usually untilthe next firing of the kerosene burner. The small restrictor performs twofunctions, it allows the liquid to enter the evaporator at a controlled level. Thisprotects the evaporator from getting flooded. The restrictor also acts as anexpansion valve which greats a pressure differential. A pressure differential isessential to the refrigeration cycle as it causes the liquid ammonia to changeits boiling point from a high pressure flash of temperature to a lower pressureflash of temperature. Without this change in pressures the refrigeration wouldnot be performed and the system would simply act as an ammonia container.

DEFINITIONS
In a text whose main purpose is to define something, the author may use words,phrases, or statements to give the meaning of a word, key words, or signal wordsto do so, therefore you need to look for them within the text. Some examples ofthese words are:
is/are (verb TO BE/s.present) means/meanis/are called what this means isis/are known as consist(s) of
is/are defined as refer(s) tois/are referred to as involve(s), imply (ies)
deals with
Definitions may be classified as:
EXPANDED: they take more than one sentence. They may encompass a paragraph, a textor passage.
SIMPLE: these are completed in one sentence
STRUCTURE OF A SIMPLE DEFINITIONLet us consider a simple definition having three main components: the term being defined, theclass to which said term belongs and the characteristics that distinguish that term from all theother members of the class.The terms usually found at the beginning of the statement , but sometimes it is found at the end,introduced by expressions such as: is calledT, is known asT, is referred to asT...
Hence, we identify two types of definition: formal and semi-formal
Formaldefinitions are represented by the equation: T= C + D
Where T = the term being definedC = the class to which the term belongsD = the distinguishing characteristics that differentiate this
term from all the other members of the same classExample:
A hydrometer is an instrument designed to measure the specific gravity of liquids
20
A defini t ion expresses the nature of a
person, a thing, a pro cess, etc.

22/31
Semi-formaldefinitions are represented by the equation: T = D ,meaning that the class is implicitly stated in the definitions, as opposed to formal definitions inwhich the class is explicitly stated.
Example:Condensation is the transformation of a vapor or gas to a liquid by cooling or an increase in
pressure or both simultaneously.
Practice:a.-Underline the TERM being defines in each of the following definitions
b. Classify them accordingly and fill in the table with their main components
1. PH is a symbol used in expressing both acidity and alkalinity on a scale whose values runfrom 0 to 14, 7 representing neutrality.
2. Torque refers to a turning or twisting force3. The ease with which a liquid is converted into a gaseous state is known as volatility.4. A servomechanism is an automatic device used for controlling large amounts of power
with a small amount of force.5. Flash point is the temperature at which a given substance will ignite.6. A control panel is an assembly of indicators and recording instruments for monitoring and

arranged within a text of English for Science and Technology. The latter allow the readerto identify the microfunctions that are present in EST paragraphs/texts in order to showthe cohesion or connection among said items and their connection to the main idea ofthe passage. They allow us to understand how ideas (secondary ideas) are linked or developedfrom one sentence to another, from one paragraph to the next. Connective elements provide us withinformation that helps further understand the main idea such as examples, comparisons,explanations, contrast, addition, cause/effect, etc.

battery, but differing from the latter in that it is designed for continuous
replenishment of the reactants consumed; i.e. it produces electricity from an
external supply of fuel and oxygen as opposed to the limited internal energy
storage capacity of a battery. Additionally, the electrodes within a battery react
and change as a battery is charged or discharged, whereas a fuel cell's electrodes
are catalytic and relatively stable.
Typical reactants used in a fuel cell are hydrogen on the anode side and
oxygen on the cathode side (a hydrogen cell). Usually, reactants flow in and
reaction products flow out. Virtually continuous long-term operation is feasible as
long as these flows are maintained. Fuel cells are often considered to be very
attractive in modern applications because of their high efficiency and ideally
emission-free use, in contrast to currently more common fuels such as methane or
natural gas that generate carbon dioxide. The only by-product of a fuel cell
operating on pure hydrogen is water vapor.

Abstract
A model is developed for the interaction of high frequency inflow disturbances with anannular cascade in swirling flows. The computational domain is decomposed into inner andouter subdomains. The outer subdomain scales with the radius of the duct R and the highfrequency approximation is used to simplify the governing equations. The inner subdomainscales with the blade chord c
