Pump Discharge Pressure Calculator

What is pump discharge pressure?

The pump discharge pressure is the pressure at the outlet of a pump, which is the point at which the water is discharged from the pump. This pressure is generated by the pump and is used to move water through a system of pipes or other conduits.

There are several factors that can affect pump discharge pressure, including the size and design of the pump, the type of fluid being pumped, the viscosity of the fluid, the resistance to flow in the system, and the elevation of the pump.

pump discharge pressure calculation Formula

To calculate pump discharge pressure, you will need to know the following information:

  • The pump flow rate (measured in gallons per minute or liters per minute)
  • The total resistance to flow in the system (measured in feet or meters of head)
  • The density of the fluid being pumped (measured in pounds per gallon or kilograms per liter)

With this information, you can use the following equation to calculate pump discharge pressure:

Pump discharge pressure = (Flow rate x Total resistance to flow) / (Density x 0.433)

The units for the pressure will depend on the units used for the other variables in the equation.

For example, if the flow rate is in gallons per minute, the total resistance to flow is in feet, and the density is in pounds per gallon, the pressure will be in pounds per square inch (psi).
