Power Generation/Hydro Power/Part5

From Wikiversity

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

Gross plant capacity (G.C):

 (in Watts) ... Equation 3.5

The firm capacity (F.C) will therefore be:

(in Watts) ... Equation 3.6

Thus the yearly gross out put:

(in kWh) ... Equation 3.7

We can also estimate the volume of flow per annum:


(in kWh) ... Equation 3.8


Where:

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