Question

1. A5 kW insulated pump is raising water to a reservoir at an elevation of 25 m from the free surface of a lake. The temperature of water increases by

0.15 deg-C. Neglecting any change inKE, determine the mass flow rate of water. Use the SL model. Watch Anim. 4.A.pumping System to understand how the energy equation can be simplified.
