Affinity laws

Calculates the flow, pressure and power varies with the flow in the pump.

Affinity laws

Alternative 1 Alternative 2
Flow q= l/s
Revolutions n= rpm
Pressure p= Pa
Effect P= kW


Choose from which cases you want to calculate the different options.


Shows what the different flows between the two different options affect revolutions, pressure rise and the impact on the pump.


Displays what the new speed of the pump is with the modified flow.


Displays what the new pressure from the pump is with the revised flow.


Displays what the new effect on the pump gets to the modified flow.
