Answer: the shaft power, in kW, produced by the turbine is 720 kW

Step-by-step explanation:

Given that;

Power extracted = 80kw

Efficiency of turbine = 0.9

efficiency of generator = 0.85

To calculate the shaft power, in kW, produced by the turbine we say;

Shaft power = Power extracted × efficiency of turbine

Shaft power = 800 kW × 0.9

Shaft power = 720 kW

therefore the shaft power, in kW, produced by the turbine is 720 kW
