In general, hydraulic horsepower (HHP) is simply pressure (P) times volumetric flow rate (Q). In US Oilfield units of pounds per square inch (psi) and gallons per minute (GPM), hydraulic horsepower (HHP) may be calculated as. (2.2)

How do you calculate pump horsepower?

The following formula can be used to calculate water horsepower (WHP).

WHP = HQ / 3960.

Where H is the change in pressure measured in height of water in feet and Q is the water flow rate in gallons per minute.

WHP = (112 x 460) / 3960 = 13.0.

How do you calculate the hydraulic power of a pump?

The hydraulic power which is also known as absorbed power, represents the energy imparted on the fluid being pumped to increase its velocity and pressure….Hydraulic Power.

How is horsepower calculated?

The equation to calculate horsepower is simple: Horsepower = Torque x RPM / 5,252.

How do you calculate hydraulic flow?

Multiply the cross-sectional area by the flow velocity, provided in unit of length over unit time squared. If the cross-sectional area and flow are truly perpendicular, the flow rate angle is zero degrees. The value you just calculated is the hydraulic flow.

What is the formula for Hydraulic horsepower?

To find hydraulic horsepower, use the equation: HP = (PSI X GPM) / 1714. PSI = Pressure in Pounds per Square Inch. GPM = Flow Rate in Gallons per Minute. Example: Calculate hydraulic horsepower when pressure.

What is the formula for hydraulic power?

The basic equation for hydraulic energy is where H = hydraulic horsepower, p = pressure (psi or kPa), q = flow rate (gal/min or L/min), and 1,714 is the conversion of (psi-gal/min) to hydraulic horsepower [ or (kPa•L/min) = 44 750] . Rig pumps are the source of hydraulic energy carried by drilling fluids.

When are hydraulic calculations required?

Hydraulic calculations are often required to prove the flow of water (or water mixed with additives like firefighting foam concentrate) through piping networks for the purpose of suppressing or extinguishing a fire .

What is the equation for horsepower?

Simplify the equation for power: 1 horsepower (hp) = 550 foot-pounds / 1 second. More generally, power = force times distance, divided by time.
