Mathematics
Awind turbine is located at the top of a hill where the wind blows steadily at 12 m/s, and stands 37 m tall. the air then exits the turbine at 9 m/s and the same elevation. find the power generated by the wind if the mass flow rate is 137 kg/s. report your answer in kw and to 2 decimal places.

Power generated = 4.315 kW
Step-by-step explanation:
Given,
speed of wind when enters into the turbine, V = 12 m/sspeed of wind when exits from the turbine, U = 9 m/smass flow rate of the wind, m = 137 kg/sAccording to the law of conservation of energy
Energy generated = change in kinetic energy
Since, the air is exiting at same elevation. So, we will consider only kinetic energy.
Energy generated in one second will be given by,
=4315.5 J
= 4.315 kJ
So, energy is generated in one second = 4.315 kJ
Power generated can be given by,
And the energy is generated is already in per second so power generated will be 4.315 kW.
