Apump is used to transfer h2o from the surface of a lake into a tank where pressure is maintained at 350 kpa. the pump operates in steady flow with an efficiency of 0.6 and has an iniet volume flow rate of 0.5m^3/s. making good engineering assumptions, do the following: a) calculate the actual power required to drive the pump. b) determine the volume flow rate at the discharge of the pump. c) show this process on a t-s diagram including the saturation curve.
