Question

how much energy has 4*10^10 m3 of water collected in a reservoir at a height of 100m from the power house? what kind of energy is that? (given mass of 1m^3 of water =1000kg

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 = 3,00

0 x 9.81 x 2.25 x 0.751 = 49,729 W = 49.7 kW
