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. A screw conveyor with the housing diameter of 15.5 cm, screw diameter of 13 cm and screw shaft diameter 3.5 cm having the length of 150 cm was constructed by
