To calculate the total required head for a booster pump, use this primary equation:
Use Excel to test maximum and minimum demand scenarios. 6. Accessing/Building Your Own Tool
Fittings (elbows, tees, valves) and filters add resistance. Instead of calculating each complex geometry, engineers use “K-factors” or the “Equivalent Length” method: booster pump head calculation xls
Understanding Booster Pump Head Calculations A booster pump increases low water pressure in a system to meet required demands. Calculating the required pump head ensures the selected pump can overcome system resistance and deliver water at the correct pressure. Pump head is the total mechanical energy a pump adds to a fluid, typically measured in feet or meters.
