Quizplus · Accepted Answer

The theoretical power available from falling water can be calculated using the formula:
P = mgh, where P is power, m is mass flow, g is the acceleration due to gravity, and h is the vertical distance.
Plugging in the values, we get:
P = 1200 x 9.81 x 110 = 1,294,680 W
Converting to kW, we get:
P = 1294.68 kW
Therefore, the best choice is A, 1,294 kW.
