Question

Water enters a turbine at a speed of 700 m / s and comes out at a speed of 400 m / s. What is the output power if it carries 2000 kg of water and its efficiency is 75%?​

Answer 1

Explanation:

If you don't mind equations the easiest way to explain how much power you could generate is to look at the equation for calculating hydropower:

P = m x g x Hnet x η

Hnet = Hgross x 0.9 = 2.5 x 0.9 = 2.25 m.

3 m3/s = 3,000 litres per second.

Power (W) = m x g x Hnet x η = 3,000 x 9.81 x 2.25 x 0.751 = 49,729 W = 49.7 kW.
