Define turbine efficiency, generator efficiency, and combined turbine-generator efficiency.
Solution to 17P
We need to define the efficiency of turbine, efficiency of generator and the combined efficiency of turbine generator system.
In turbines mechanical energy is extracted from the fluid and it is used to run the shaft. When more of mechanical energy is extracted from the fluid to run the shaft, we will say that the efficiency of turbine is high.
Efficiency of turbine is the ratio of mechanical energy output to the mechanical energy extracted from the shaft.
