There are four equally powerful units in a hydroelectric power plant with a total power of 160 MW. Generators in each unit have 48 poles and 50 Hz frequency and their efficiency is 97%. Turbine efficiency is 91%, and the head efficiency is 98%.
The shafts of the water turbines that drive the generators will be deemed to be directly connected to the generator shafts. Since the flow of water entering the turbines in this power plant is 53 m^3 / s;
a) Find the turbine specific rotation speed in terms of (rpm).
b) Find the power of the water entering the turbines in (kW).
c) Calculate the annual energy that can be produced in this plant.
