A river flowing steadily at a rate of 240 m3/s is considered for hydroelectric power generation. It is determined that a dam can be built to collect water and release it from an elevation difference of 50 m to generate power. Determine how much power can be generated from this river water after the dam is filled. (

power generated = 117.72 MW

Explanation:

given data

flow rate of river = 240 m³/s

height above the surface lake = 50m

solution

we get power generated that is express as

power generated = distance × acceleration due to gravity × elevation head × density of water  1

power generated = 240 × 9.81 × 50 × 1000

power generated = 117.72 MW
