A pump draws water from a reservoir and conveys it to another reservoir 30 m above. The suction pipe is 100 mm in diameter and 10 m long while the delivery pipe is 100 mm in diamter and 150 m long. if the the velocity in the pipe is 3 m/s, the friction factor of the pipe 0.008, and the pump and motor efficiencies are 85 % and 92 %, respectively. Assume height of pump/motor negliglible. Q1. Calculate the gauge pressure at the pump's inlet (at C) (kN/m2) Q2. Calculate the gauge pressure at the pump's outlet (at D) (kN/m2) Q3. Calculate input power to motor (kW)
