Booster Pump Head Calculation Xls May 2026

Provide one worked example in the sheet using typical values:

The pump head (H) can be calculated using the following basic formula:

[ H = \frac\Delta P\rho g + H_e + H_f ]

Where:

TDH = Hₛ + H_d + H_f + H_v

Where:

First, convert ΔP to feet of head: [ 50 , \textpsi \times \frac144 , \textin^21 , \textft^2 \div 62.4 , \textlb/ft^3 \div 32.2 , \textft/s^2 \approx 358.5 , \textft ]

Then, calculate total head: [ H = 358.5 , \textft + 100 , \textft + 10 , \textft = 468.5 , \textft ] Provide one worked example in the sheet using

| Issue | Why It Matters | |-------|----------------| | Hidden or unprotected formulas | Users may accidentally break calculations. | | No friction loss for all pipe materials | Some sheets assume only PVC or steel. | | Ignores temperature effects | Viscosity and density changes affect pump performance. | | No allowance for future fouling | Pipes scale up → higher friction loss over time. | | Minor losses underestimated | Many sheets use only 10–20% of friction loss, which is often too low for systems with many valves/fittings. | | No NPSH margin | Should have a safety factor (e.g., 0.5–1 m extra). | | Doesn’t check pump operating point | Without pump curves, you might select an undersized pump. |
