At night, water is pumped from a treatment plant reservoir through distributing piping to an elevated storage tank. Assume no other withdrawals from the system. The water surface in the supply reservoir is at 3m elevation, the lift pump elevation is 6m, the water elevation in the elevated tank is 42m. The pipe network maybe considered equivalent to 1500m of 250mm diameter. Use C=100. There is a supply of 60 Liters/sec. to the tank. a. Compute the head loss of the 250mm diameter pipe. b. Compute the pump discharge pressure required to supply a flow of 60L/s to the tank, c. Compute the slope of the energy gradient
