The Pump Overall Efficiency (HPout/HPin) equation calculates a pump's Overall Efficiency (Effov) in percent (%) given it's Output Power (HPout) and Input Power (HPin).
INSTRUCTIONS: Choose units and enter the following:
(HPout) Output power in horsepower (hp)
(HPin) Input power in horsepower (hp)
This equation returns the Pump's Overall Efficiency (Effov) in percent.
