Water is pumped from a reservoir (water surface elevation = 111 m) and delivered to a higher elevation of 150.2 m as a free discharge through a 500 mm diameter pipe. the pump which is rated at 150 kw has a 70% efficiency. if the head loss in the pipe system is given by hl (m) = 46.42 q^2 (q in m^3/s). determine the discharge from the pump
