TDH = H_geo + H_friction + (P_discharge - P_suction) * 10.2 booster pump calculation excel
Download a template or build one using the formulas above. Test it against a known installed pump. Refine it with your local pipe material data. Then use it on every project. Have you built your own pump sizing spreadsheet? What’s the most useful feature you’ve added? Let’s discuss in the comments. =CEILING(P_m, 1
NPSHa = P_suction*10.2 - H_vapour - H_suction_friction Then use it on every project
A booster pump isn’t just a "water pusher." It is the critical component that ensures adequate pressure and flow in water supply systems—from high-rise buildings and industrial plants to irrigation networks. Under-sizing leads to low pressure at fixtures; over-sizing leads to energy waste, premature wear, and cavitation.
NPSHa = (D10*10.2) - 0.34 - H_friction_suction Condition: NPSHa must be > NPSHr (from pump curve) by at least 0.5 m. Once you have TDH and Q, calculate hydraulic, shaft, and motor power.
