| Parameter | Unit | Description | Typical Value | | :--- | :--- | :--- | :--- | | Flow Rate (Q) | m³/h or GPM | Peak demand (fixture units, sprinkler heads, etc.) | Variable | | Suction Pressure (P_suction) | bar or psi | Pressure available at pump inlet (from city main or tank) | 2.5 bar | | Required Discharge Pressure (P_discharge) | bar or psi | Pressure needed at the highest/farthest fixture | 4.0 bar | | Elevation Difference (H_geo) | m or ft | Vertical distance from pump to highest point | 25 m | | Pipe Length (L) | m | Total length of the longest run | 150 m | | Pipe Diameter (D) | mm or in | Nominal bore | 80 mm | | Friction Factor (f) | dimensionless | Darcy-Weisbach or Hazen-Williams C-factor | 0.02 (or C=130) |
Use data validation dropdowns for units (e.g., m vs. ft) and apply CONVERT functions to standardize all inputs to SI or US customary internally. Part 2: Key Calculations (The Engine of Your Spreadsheet) In a hidden or dedicated column, perform these critical steps. 2.1 Total Dynamic Head (TDH) – The Master Formula The pump must overcome three things: elevation, friction, and velocity head (usually negligible). The core Excel formula for TDH (in meters of water column) is: booster pump calculation excel
#EngineeringExcel #PumpSizing #HydraulicCalculations #BoosterPump #ExcelForEngineers | Parameter | Unit | Description | Typical
Cell A10: Elevation (m) = 25 Cell B10: Friction Loss (m) = Calculate per 2.2 below Cell C10: P_discharge (bar) = 4.0 Cell D10: P_suction (bar) = 2.5 Cell E10: TDH (m) = A10 + B10 + (C10 - D10)*10.2 This is where Excel shines for iterative design. Your Excel sheet should start with a clear Input tab
In this post, I’ll break down the key calculations every booster pump sizing spreadsheet must include, complete with formulas and logic. Your Excel sheet should start with a clear Input tab. Without accurate data, the best formulas are useless.
The most reliable way to avoid these pitfalls? A well-structured . While dedicated software exists, Excel remains the industry workhorse because it is transparent, customizable, and universally accessible.
