Mechanical Operations For a non-spherical particle, the sphericity Has the dimension of length Is the ratio of volume of a sphere having the same surface area as the particle to the actual volume of the particle Is defined as the ratio of surface area of a sphere having the same volume as the particle to the actual surface area of the particle Is always less than 1 Has the dimension of length Is the ratio of volume of a sphere having the same surface area as the particle to the actual volume of the particle Is defined as the ratio of surface area of a sphere having the same volume as the particle to the actual surface area of the particle Is always less than 1 ANSWER DOWNLOAD EXAMIANS APP
Mechanical Operations During agitation of liquids, the Froude number is used to account for the effect of surface (e.g., the centre vortex) on the power number 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 independent for the curves between power number and Reynolds number in baffled system Froude number is used to account for the effect of surface (e.g., the centre vortex) on the power number 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 independent for the curves between power number and Reynolds number in baffled system ANSWER DOWNLOAD EXAMIANS APP
