Water is to be pumped from a lake up to a pool. The pump power is 5 kW and the
pump has an efficiency of 72%. The surface of the pool is 25 m above the surface of
the lake. The friction pressure drop in the pipe system is 39.24 kPa.
The density of water is 1000 kg / m. The pressure over the lake and over the pool is
atmospheric pressure.
1. Calculate the pumping work performed.
2. How big is the pressure difference across the pump, üp ?
3. Calculate the volume flow.
