Water at 20C is pumped at a flow rate of 1 kg/sec from a storage tank through 100 meters of 3 cm diameter pipe. The pipeline has two globe valves which are fully open and three 90 elbows. Water is discharged into another tank through a spray nozzle. The discharge is at a height of 20 meters above the level of water in the storage tank. The pressure required at the nozzle entrance is 3 kg/m? gauge. Estimate: (1) The energy loss due to friction. (2) Pump work required
