A closed loop conveyor is to be designed to deliver parts from a single load station to a single unload station. The handling system will provide delivery function only, no storage. The load and the unload station separated by a distance of 300ft. It is assumed that the forward loop and the return loop will be of equal length. The speed of the conveyor 150 ft/min. Time required to load parts on to and unload parts from the conveyor at the respective stations are TL= TU= 0.15 min. The specified flow rate of the parts that must be delivered between the two stations is 300 parts per hr. Determine the required parameters of the conveyor system that will achieve this flow rate.  Determine the values of number of carriers, number of parts per carrier and spacing between carriers.
