If a plant has an effective capacity of 6500 and an efficiency of 88%, what is the actual (planned) output? 3. Material delays have routinely limited production of household sinks to 400 units per day. If the plant efficiency is 80%, what is the effective capacity? 4. Under ideal conditions, a service bay at Fast Lube can serve 6 cars per hour. The effective capacity and efficiency of service bay are 5.5 and 0.88 respectively. What is the minimum number of service bays Fast Lube needs to achieve an anticipated of 200 cars per 8-hour day? 5. A work cell at a Laundry has workstation with 2 machines.
