It is required to pump cooling water from a storage pond to a condenser in a process plant situated 10m above the level of the pond. 200m of 74.2 mmid pipe
is available and the pump has the characteristics given below. The head loss in
the condenser is equivalent to 16 velocity heads based on the flow in the 74.2mm
pipe. If the friction factor is 0.003, estimate the rate of flow and power to be
supplied to the pump assuming 50% efficiency.
