The pressure rise across a pump P (this term is proportional to the head developed by the pump) may be considered to be affected by the fluid density ρ, the angular velocity ω, the impeller diameter D, the volumetric rate of flow Q, and the fluid viscosity μ.

Find the pertinent dimensionless groups, choosing them so that P, Q, and μ each appear in one group only.

Find similar expressions, replacing the pressure rise first by the power input to the pump, then by the efficiency of the pump.
