Question: Calculate the minimum power required to pump 0 . 0 2 m 3 / s into a tank where pressure is 2 0 0 kPa.

Calculate the minimum power required to pump 0.02 m3/s into a tank where pressure is 200
kPa. If the pump operates with a 65% isentropic efficiency, what is the actual power needed to
drive this pump? Draw the T-s diagram for the minimum and actual work processes.
