Mass pouring = 100 kg/s
height = 100m

Maximum energy that can be delivered per second = mgh
⇒ Max. Power = 100kg/s × 9.8 m/s² × 100m
⇒ Max. Power = 98000 J/s
⇒ Max. Power = 98 kJ/s = 98 kW

But all the energy is not transferred from water. The water which fell still has some Kinetic energy. We normally take 50% efficiency. So 50% of maximum Power is delivered.

So power delivered = 98 × (50/100) = 49 kW
