Four rivers have the same volume of water flow over time but fall from different heights to power hydroelectric dams. Which dam would provide the most hydroelectric power?

Question

a
dam C: fall height of 135 feet
b
dam B: fall height of 75 feet
c
dam D: fall height of 100 feet
d
dam A: fall height of 175 feet

Answer 1

d. Dam A with a fall height of 175 feet would provide the most hydroelectric power. The power generated by a hydroelectric dam depends on the volume of water flow and the height from which it falls. The higher the fall height, the more potential energy the water has, and the more power it can generate when it falls. Therefore, the dam with the highest fall height (dam A) would produce the most hydroelectric power.
