Hydraulic Horsepower

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

 

Hydraulic Horsepower formulas

\(\large{ HHP = \frac{ Q \; p }{ 1714 }   }\)	(required to drive hydraulic pump)
\(\large{ HHP = \frac{ Q \; p }{ 1714 \; \eta_p }   }\)	(required to drive hydraulic pump)
\(\large{ HHP = \frac{ h \; Q \; SG }{ 3956 }   }\)

Where:

\(\large{ HHP }\) = hydraulic horsepower

\(\large{ Q }\) = flow rate (GPM)

\(\large{ h }\) = head

\(\large{ p }\) = pressure (PSI)

\(\large{ \eta_p }\)  (Greek symbol eta) = pump efficiency

\(\large{ SG }\) = specific gravity
