Power Generation/Hydro Power/Part4

Below are equations used for calculations involving this kind of power station:

Weight of the water head:

 (in Kg) ... Equation 3.1

The potential energy of the water head:

(in Joules) ... Equation 3.2

Thus the equivelent electrical energy will be:

(in kWh) ... Equation 3.3

Electrical enegry can also be expressed as:

(in kWh) ... Equation 3.4

Where:

  • m = mass (in Kg)
  • g = constant ≈
  • h/H = water head height (metres)
  • ρ = density of water ()
