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.

Power is consumed by a pump fan or compressor in order to move and increase the pressure of a fluid. The power requirement of the pump depends on a number of factors including the pump and motor efficiency the differential pressure and the fluid density viscosity and flow rate. This article provides relationships to determine the required pump power.
Chat OnlineOct 01 1997 1. A theoretical model for the torque requirement of a screw feeder is developed by applying principles of powder mechanics to a moving material element within a pitch. The model indicates that the torque requirement is proportional to the stress exerted on the feeder by the bulk solid in the hopper and to the third power of the screw diameter. 2.
