.
), measured in watts, is determined by this expression, which is derived from definition of mechanical energy and energy efficiency:
(1)
- Energy efficiency, no unit.
- Density, measured in kilograms per cubic meter. 
- Gravitational acceleration, measured in meters per square second.
- Fluid column, measured in meters.
- Volume flow, measured in cubic meters per second. 
, 
, 
, 
and 
, then the estimated electric power output of this plant is:
