Answer:
Total power generation will be 291.465 MW
Explanation:
We have given that river is flowing at rate of V =
Average speed v = 3 m/sec
Height h = 58 m
We know that total mechanical energy is given by
E = KE +PE
Energy per unit mass
Total power generation from the river is given by
So
Answer: D. The feather experiences more fluid friction than the ball.
Hope this helps!
