Power calculation for a Pico hydro system

Electrical Power output(W)=   head ×flow rate×gravitational accelaration ×system overall efficiency

  • Head-in meters
  • Flow rate-in liters per second
  • Gravitational acceleration-9.81ms^(-2)
  • system Overall efficiency-0.40

Example:

If the water flow is 15 liters per second and head is 20m

Electrical Power output=  20m×15  l/s×9.81ms^(-2)  ×0.4
Electrical Power output=1177.2W
