At a constant speed of the centrifugal pump . it __________ the impeller diameter.

In the Newton's law range, the terminal velocity of a solid spherical particle falling through a stationary fluid mass is __________ the fluid viscosity.

In case of isentropic flow, the speed of sound in an ideal gas is proportional to (where M = molecular weight of the gas)

Various efficiencies of a centrifugal pump are related as (where, ηm = mechanical efficiency ηv = volumetric efficiency. ηma = manometric efficiency ηo = overall efficiency)
