Required Power = 140 lbs x 50 fpm = 7,000 ft-lbs/min. Convert that to a useful unit of measure. One horsepower (HP) equals 33,000 ft-lbs/min. Therefore, our power requirement can be converted as follows. Required Power = (7,000 ft-lbs/min)/(33,000 ft-lbs/min per HP) Required Power = 0.2 HP. Now we can select an appropriate conveyor drive system.
