This will involve a detailed report and further questions. The simplest strategy is to do the lab.] Notes For the First Year Lecture Course: An Introduction to Fluid Mechanics School of Civil Engineering‚ University of Leeds.

ABSTRACT This experiment was carried out to determine the relationship between the pressure and the temperature of saturated steam in equilibrium. Besides that this experiment was also done to demonstrate the vapor pressure curve. The marcet Boiler was used for this experiment. When the pressure increases‚ the temperature also increases. Therefore‚ the relationship of pressure and temperature is directly proportional. The derived formulae and the data were used to calculate the slope. The dT/dP

Effect of various factors like seal balance‚ face pressure‚ temperature and lubrication on performance of seal and probable causes of seal leakage with their corrective action has also been described. Mechanical seals arrest the leak from shaft where it comes out of the casing. They work satisfactorily to seals almost any liquids‚ operate under full vacuum to 80 Bar pressure and temperature from 100 to 840oC. It can handle shaft speeds up to 3600 RPM and special

On a microscopic level‚ the molecules (or atoms) in a gas are separated by large distances and are in constant‚ random motion. When dealing with gases‚ the Ideal Gas Law equation is the most famous equation used to relate all the factors in dealing and solving the problem. The four factors or variables for gas are: pressure (P)‚ volume (V)‚ number of mole of gas

transmission of fluid-pressure is a principle in fluid mechanics that states that pressure exerted anywhere in a confined incompressible fluid is transmitted equally in all directions throughout the fluid such that the pressure ratio (initial difference) remains the same.[1] The law was established by French mathematician Blaise Pascal.[2] Contents [hide] 1 Definition 2 Explanation 3 Applications 4 See also 5 References Definition[edit source | editbeta] Pressure in water and air.
