The value of NPSHmin for a pump is given by the vendor to be 20 ft. Water is being pumped from a reservoir at a rate of 25 cfs. The water level in the reservoir if 6 ft above the pump. Atmospheric pressure is 14.7 psia and the water temperature is 40 F. If the head loss in the suction side of the pump piping is 4 ft, determine whether or not the pump will cavitate.

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
