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 = 9.8 ms–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
