How to calculate head in feet
Web24 mei 2024 · The operating point for any pump is where the pump curve intersects with the system curve. Your pressure can be converted into feet of head by multiplying by 2.31. 12 x 2.31 = 27.7 feet of head for the pressure side. 3 hp would create more than 12 psi, so the pump might be on low speed of two speeds or have a smaller impeller. WebPump Head Formulas: Imperial Units: H = (2.31 ( Pd – Ps) / SG) + (Vd 2 – Vs 2) / 2g + (Zd – Zs) – Hf where: H = pump head, ft. Hf = friction loss, ft. PS = suction pressure, psia. Pd = …
