At a hydroelectric power plant, the water pressure head is at a height of 300 m and the water flow available is 100 m3s−1. If the turbine generator efficiency is 60%, estimate the electric power available from the plant (g = 9.8ms−2 ).
The power generated is P=mgh=ρV×gh=1000×100×9.8×300=294MW
The power available is P=0.6×1000×100×9.8×300=176.4MW
