During agitation of liquids, the

Froude number is independent for the curves between power number and Reynolds number in baffled system

Power number becomes independent of impellers Reynolds number at high Reynolds number, but is dependent on the geometry of the impeller

Froude number is used to account for the effect of surface $($e$.$g$.,$ the centre vortex$)$ on the power number

All $($A$),($B$)$ and $($C$)$
