Screw Conveyor Engineering Guide - Horsepower Calculation

Thus TSHP is calculated as follows: TSHP = 0.256 + 1.320 = 1.576 H.P. Assuming a drive efficiency of 85% resulting in a total drive horsepower of 1.853, a standard 2 horsepower motor would be selected for the drive input. The horsepower required for the above conveyor may also be determined graphically by the use of the two horsepower nomographs.
