Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

Show complete solution and formulas used. Show the schematic diagram too. Calculate the required pipe diameter to avoid cavitation, if the pump delivers Q = 30US gallon/min water from a closed tank, where the pressure (above the water level) is p = 40kPa. The equivalent length of the smoothened concrete pipe on the suction side is 12m while the suction flange of the pump is 8m below the water level. The vapour pressure at the given water temperature is 2.8kPa. The required net positive suction head is NPSHr = 3.2m.
