Mechanical Operations Work index is defined as the Gross energy (kWh/ton of feed) needed to reduce very large feed to such a size that 80% of the product passes through a 100 micron screen Energy (kWh/ton of feed) needed to crush small feed to such a size that 80% of the product passes a 200 mesh screen Energy needed to crush one ton of feed to 100 microns Energy needed to crush one tonne of feed to 200 microns Gross energy (kWh/ton of feed) needed to reduce very large feed to such a size that 80% of the product passes through a 100 micron screen Energy (kWh/ton of feed) needed to crush small feed to such a size that 80% of the product passes a 200 mesh screen Energy needed to crush one ton of feed to 100 microns Energy needed to crush one tonne of feed to 200 microns ANSWER DOWNLOAD EXAMIANS APP
Mechanical Operations During agitation of liquids, the 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 All of these Power number becomes independent of impellers Reynolds number at high Reynolds number, but is dependent on the geometry of the impeller 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 All of these Power number becomes independent of impellers Reynolds number at high Reynolds number, but is dependent on the geometry of the impeller ANSWER DOWNLOAD EXAMIANS APP
