(Friction Head): Pressure loss as water moves through pipes, valves, and fittings. In Excel, this is often calculated using the or Hazen-Williams equations. Hvelocitycap H sub v e l o c i t y end-sub

= Hazen-Williams roughness coefficient (e.g., 140 for PVC, 100 for unlined cast iron) = Inside pipe diameter (meters)

For a simple system:

Make a column (G1:G10) with flows: 0, 2, 4, 6, 8, 10, 12 m³/hr. Compute TDH for each. Plot X-Y scatter chart. Compare to pump data. (Friction Head): Pressure loss as water moves through

Create a K-factor and roughness reference table so your sheet automatically calculates friction based on pipe material.

Occurs when the liquid source is above the pump centerline (entered as a positive value that assists the pump). 2. Static Discharge Head ( Hdcap H sub d Compute TDH for each

: Create a section where you can input the known parameters such as flow rate, required pressure increase, fluid density, elevation head, and estimated friction losses.

(Inlet Pressure / Suction Head): The existing pressure entering the pump from the city main or a storage tank. Booster pumps boost existing pressure, so subtracting Hincap H sub i n end-sub prevents over-sizing. Step-by-Step Calculation Guide Step 1: Determine the Design Flow Rate (
