The
amount of power required to drive a pump intensifies as the desired pressure and
flow increases. Also it generally
requires a gasoline engine
rated at approximately twice the horsepower of
an electric motor to
get the same performance out of the same pump under continuous operation.
To
figure out what horsepower is needed to operate a pump at a certain, desired
flow and pressure, you just have to multiply the GPM (gallon
per minute)...
