Pressure
How is it measured in process industry? PSIG – Pounds per Square Inch Gauge
Pressure within a system without taking into account for atmospheric pressure
PSIA – Pounds per Square Inch Absolute This is the SUM of the pressure within the system and
the atmospheric pressure

Pressure of Fluids
So what affects the pressure of a fluid?
Pressure of Fluids
So what affects the pressure of a fluid? Temperature -
Pressure of Fluids
So what affects the pressure of a fluid? Temperature and pressure are Directly proportional to
each other. So what does that mean?
Pressure of Fluids
So what affects the pressure of a fluid? Temperature and pressure are Directly proportional to
each other. So what does that mean? As temperature increases so does pressure and if
temperature decreases so too does pressure. Example
Pressure of Fluids
So what affects the pressure of a fluid? Temperature and pressure are Directly proportional to
each other. So what does that mean? As temperature increases so does pressure and if
temperature decreases so too does pressure Volume is indirectly proportional to both temperature
and pressure. So what does that mean?

each other. So what does that mean? As temperature increases so does pressure and if
temperature decreases so too does pressure Volume is indirectly proportional to both temperature
and pressure. So what does that mean? As volume is decreased temperature and pressure will
increase and if volume is increased then temperature and pressure will decrease
Gravity of Fluids
Gravity – expresses the weight of a fluid
Gravity of Fluids
Gravity – expresses the weight of a fluid Liquid densities are typically compared to water

Gravity – expresses the weight of a fluid Liquid densities are typically compared to water
API (American Petroleum Institute) Gravity measures liquid hydrocarbon densities to water
Gas or vapor densities are compared to airSpecific Gravity – is a comparison of the fluid density of
compound to the fluid density of a different compound that are both at the same temperature
Miscibility of Fluids
Miscible – liquids of different specific gravities are able to form a mixture.
Miscibility of Fluids
Miscible – liquids of different specific gravities are able to form a mixture.
Immiscible – liquids of differing specific gravities that are not capable of mixing
