Two conveyors having $6^$ prime prime RC values are used to transport toteboxes horizontally $300\text{'}$ from manufacturing to work $-$in$-$ process storage. The first conveyor is a $200\text{'}$ long chain$-$driven roller conveyor with a speed of $200$ fpm$.$ Cartons are fed directly from the roller conveyor to a roller$-$supported belt conveyor. Toteboxes weigh $35$ pounds each, and they are $28^$ prime prime long. The clearance between toteboxes on the first conveyor is $12^$ prime prime The second conveyor is operated at a speed that will yield a $18^$ prime prime spacing between cartons. The WBR dimension for both conveyors is $27.$ Solve for the horsepower requirement for the second conveyor $.$
