Mechanical Operations 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 All of these Froude number is used to account for the effect of surface (e.g., the centre vortex) on the power number 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 All of these Froude number is used to account for the effect of surface (e.g., the centre vortex) on the power number ANSWER DOWNLOAD EXAMIANS APP
