CONCLUSION

1. From the result obtained, make a summary of this experiment.In open channel, the free movement is existed between the flowing liquid (water) with fluid on it (atmosphere). The pressure in liquid is hydrostatic which is the rate of pressure is directly to the height of the liquid.

2. In the experiment, why the value of Cd experiment and the Cd theoretical are different?Because when the experiment is carried out, there were errors that cannot be avoid when carrying the experiment.

3. What is the relationship between the actual discharge and H?The actual discharge is increased when the height of the open channel is increased.

4. How does the process of calibration V-notch done?The value of Cd has to be calibrated in process of calibration of V-notch.

5. In real situations, where this hydraulic structure can be found?River and drainage system.

CONCLUSION

1. Explain why there is a different between W1 and Wa? There is a different between W1 and Wa is the error of the experiment.

2. In your opinion, what is the best step to solve the problems whole this experiment is done?In my opinion, the best steps to solve the problems are to carry the experiment accurately and measure all the apparatus and materials correctly.

DISCUSSION

1. From the results, draw conclusion and recommendation of the experiment.The volume of the solid can be determined by losing of the weight when the solid is immersed into the liquid. The specific density in liquid can be determined by determine the distance in hydrometer buoyancy.

2. State the uses of Archimedes Principle in Engineering.Archimedes principle is of uses in engineering the density of metals and alloys. A body is immersed in water or liquid will displace its own volume of fluid. But its apparent mass will decrease by the mass of water it displaces. Therefore we may determine the apparent density of the body, in terms of grams per unit volume. Consider a cube of metal immersed in water.
