Hydraulic Horsepower Formula

HHP=Qp1714ηp     (Hydraulic Horsepower)

Q=HHP1714ηpp

p=HHP1714ηpQ

ηp=QpHHP1714

Symbol English Metric
HHP = Hydraulic Horsepower lbfft/sec J/s
Q = Flow Rate ft3/sec m3/s
p = Pressure lbf/in2 Pa
ηp  (Greek symbol eta) = Pump Efficiency dimensionless dimensionless

hydraulic horsepower 1Hydraulic horsepower, abbreviated as HHP, is the power generated by a hydraulic system.  It is a measure of the rate at which a hydraulic system can perform work by moving fluid under pressure.  The concept is particularly relevant in industries where hydraulic systems are commonly used, such as in heavy machinery, industrial equipment, and hydraulic presses.  Understanding hydraulic horsepower is important for selecting the right hydraulic components and designing systems that can meet the power requirements of specific applications.

Keep in mind that this formula provides the theoretical hydraulic power and doesn't account for losses in the system due to factors such as friction, heat, and inefficiencies in components like pumps and motors.  Actual hydraulic power output may be less than the calculated hydraulic horsepower due to these losses.
