Duty point
Awaiting Valid Duty Parameters
Adjust the parameters on the left to compute live hydraulic values, ranges, and sizing verdicts.
Want the motor size confirmed against the curve?
Our engineers verify the duty point and motor selection for chemical, pharma, and process pumps across Gujarat.
How the estimate works
From duty point to motor power
The calculator converts litres per minute to cubic metres per second and applies the hydraulic power relationship P = ρ × g × Q × H. It then divides by pump efficiency to estimate motor input power and converts kilowatts to horsepower. The result is a preliminary estimate — final selection should include the pump curve, service factor, starting method, viscosity, temperature, and plant standards.
Technical & Operational FAQs
Q1.What inputs are needed for pump power sizing?
You need flow rate, total head, pump efficiency, and the liquid specific gravity. The calculator estimates hydraulic power and the motor power needed after efficiency losses.
Q2.Is this calculator a final motor selection?
No. It is a preliminary estimate. Final selection should include the pump curve, service factor, starting method, viscosity, temperature, and plant standards.
