The diagram above shows the set up for a pump and water turbine unit at a power generation company in Point Lisas. i. The water has a temperature of 25°C and the head losses accumulated by the valve and fittings is 2 N.m/N between points A and B. If the flow rate is 0.02m³/s and the pump is 75% efficient, determine the power put into the pump. Determine the energy removed by the turbine and use it to determine the mechanical efficiency of the turbine given that 2450W of power is outputted from the turbine. ii.

The diagram above shows the set up for a pump and water turbine unit at a power generation company in
Point Lisas.
i.
The water has a temperature of 25°C and the head losses accumulated by the valve and fittings is
2 N.m/N between points A and B. If the flow rate is 0.02m³/s and the pump is 75% efficient,
determine the power put into the pump.
Determine the energy removed by the turbine and use it to determine the mechanical efficiency of
the turbine given that 2450W of power is outputted from the turbine.
