Question:

Dimensional analysis for pump power—E. The power P needed to drive a particular type of centrifugal pump depends to a first approximation only on the rotational speed N, the volumetric flow rate Q, the impeller diameter D, and the density ρ of the fluid being pumped, but not its viscosity. What dimensionless groups could be used for correlating P in terms of Q?
