A 1 inch diameter nozzle there is a water flows under 400ft head to operate a turbine. There is 90% efficient of turbine and connected to a 94% efficient generators. Find the power output in kilowatts.
The water flows through a nozzle of 1 inch = 0.0254 m
head loss 400 ft. = 121.92 m
Area = = 3.142
Assuming that the flow rate is 3 m/s the mass of water of = 3000 kg/s
Hydropower W =
assuming the that the head loss = 10%
the net head 121.92 = 109.728 m
