2. Water from a reservoir is pump over a hill through a pipe 900mm in diameter and a pressure of one kg/cm² is maintained at the pipe discharge where the pipe is 85m from the pump centerline. The pumps have a positive suction head of 5m. Pumping rate or the pump at 1000 rpm is 1.5m³/sec. Friction losses is equivalent to 3m of head loss. What is the head that should the pump cover for the system?
