Motor Horsepower

Motor horsepower, abbreviated as \(MHP\), is a measure of power or the rate of doing work.

 

Motor Horsepower formulas

\(\large{ MHP = \frac{ \tau \; RPM }{ 63025 }   }\)
\(\large{ MHP = \frac{ GPM \; PSI }{ 1714 \; \eta }   }\)
\(\large{ MHP = \frac{ V \; I \; \eta }{ 746 }   }\)

Where:

\(\large{ MHP }\) = motor horsepower

\(\large{ I }\) = current

\(\large{ GPM }\) = gallon per minute

\(\large{ PSI }\) = pounds per square inch

\(\large{ \eta }\)  (Greek symbols eta) = efficiency %

\(\large{ RPM }\) = revolution per minute

\(\large{ \tau }\)  (Greek symbol tau) = torque

\(\large{ V }\) = voltage
