Question 13
2
Rocket propulsion company is considering the expansion of a
solid propellant manufacturing process by adding more 1-ton-
capacity curing furnaces. Each batch (1 ton) of propellant must
undergo 30 minutes of furnace time; including load and upload
operations. However, the furnace is used only 80% of time due to
power restrictions in other parts of the system. The required
output for the new layout is to be 16tons per shift (8hours). Plant
(system) efficiency is estimated at 50% of system capacity.
Determine the number of furnaces required.
