Enter the pressure difference between inlet and outlet, the flow rate between inlet and outlet, the height difference between inlet and outlet, and the density of the fluid into the calculator to determine the condenser pump head.

Condenser Pump Head Formula

The following formula is used to calculate a Condenser Pump Head.

CPH = (p2-p1)/p*g + (c2-c1)/2*g+(z2-z1)

  • Where CPH is the Condenser Pump Head (m)
  • p2-p1 is the difference in pressure between the inlet and outlet
  • p is the density of the fluid (kg/m^3)
  • c2-c1 is the difference in velocity between the inlet and outlet (m/s)
  • g is the acceleration due to gravity (9.81m/s^2)
  • z2-z1 is the difference in height between the inlet and outlet (m)

This formula can be used for any pump, not just a condenser pump.

What is a Condenser Pump Head?

A Condenser Pump Head is a measure of the total amount of “head” that a condenser pump has based on the pressures, flow rates, and heights of the inlet and outlet of the pump.

How to calculate Condenser Pump Head?

Example Problem:

The following example outlines the steps and information needed to calculate a Condenser Pump Head.

First, determine the difference in pressure between the inlet and outlet. In this example, the difference is 10 N/m^2.

Next, determine the difference in flow velocity between the inlet and outlet. In this case, the difference in flow is 5m/s.

Next, determine the difference in height between the inlet and outlet. For this pump, the height difference is 1m.

Next, determine the density of the fluid. This pump is running water, so the density is 1.225 kg/m^3.

Finally, calculate the Condenser Pump Head using the formula above:

CPH = (p2-p1)/p*g + (c2-c1)/2*g+(z2-z1)

CPH = 10/1.225*9.81 + 5/2*9.81+1

CPH = 2.086 m
