How much power is theoretically available from a mass flow of 1 000 kg/s of water that falls a vertical distance of 100 m?
A)980 kW
B)98 kW
C)4 900 W
D)980 W

Question

Quizplus · Accepted Answer

The theoretical power available from a mass flow of water falling a vertical distance is given by the equation: 
Power = (mass flow rate) x g x h, 
where g is the acceleration due to gravity (9.81 m/s^2) and h is the height of the fall (in meters). 
Substituting the given values, 
Power = (1000 kg/s) x (9.81 m/s^2) x (100 m) 
Power = 981,000 W = 980 kW (rounded to the nearest whole number) 
Therefore, option A is the correct answer.
