What is impeller?

Impeller is a rotating component of a centrifugal pump that accelerates fluid outward from the center of rotation, thus transferring energy from the motor that drives the pump to the fluid being pumped.

How to Calculate Mean diameter of impeller?

Mean diameter of impeller calculator uses Mean diameter of impeller=sqrt(((Diameter of impeller at inlet^2)+(Hub diameter of impeller^2))/2) to calculate the Mean diameter of impeller, The Mean diameter of impeller formula is defined as the square root of half of sum of squares of impeller inlet diameter and hub diameter of inlet. Mean diameter of impeller and is denoted by D_m symbol.
