Condensate return pump head calculator

Sum receiver pressure difference, elevation and friction for water-density condensate; use actual density for hot condensate design.

Units

H_{\text{req}} = 2.31 \times \left(P_{d} - P_{r}\right) + z + H_{f}

Calculator

Enter the values you know and leave one box empty. Calculate finds the empty one, the result or any input.

Given

H_{\text{req}} = 2.31 \times \left(32 - 8\right) + 18 + 9 = 82.44
