Multistage Pumps When to use these over single stage models? Due to their relative simplicity of design centrifugal pumps are the most common pump type in the market. Centrifugal pumps are categorised into either single or multistage pumps both of which have their uses. ### How to calculate the efficiency of multistage centrifugal ...

Mass flow qm = q (t / h or kg / s) Because the power of the multi-stage pump N (KW) = head (m) × flow (m3 / s) × 1000 (weight of water Kg / m3) ÷ 102 (power conversion factor) ÷ (efficiency of multi-stage pump) by This can seek the efficiency of multi-stage pumps. ### Pump flow rate calculation - Multistage PumpBoiler Feed ...

Jun 19 2019 · Submersible pump flow calculation formula: 60HZ flow × 0.83 = 50HZ flow 60HZ lift × 0.69 = 50HZ lift 60HZ power ÷ 1.728 = 50HZ motor power motor output power = Q (flow) × H (head) / 367.2 / efficiency × 1.15 motor output power = shaft power × 1.15 pump efficiency = Q × H × 0.00272 / motor power Q represents flow; H represents the head; 0.83 / 0.69 / 1.728 / 367.2 / 1.15 / 0.00272 are all
