Question

System efficiency is expressed as ratio of

• A. Actual measured output to the designed capacity
• B. Actual measured output to the installed capacity
• C. Actual measured output to the system capacity
• D. Actual measured output to the rated capacity

Answer 1

Answer:

C. Actual measured output to the system capacity

System efficiency is the ratio of actual measured output to the system capacity. The capacity of a manufacturing unit can be expressed in units of output or man/machine hours. Design capacity is the planned rate of output, while system capacity is the maximum output the system can produce. The actual output is affected by factors like demand, equipment failure and labor inefficiency. The rated capacity is based on the highest production rate established by actual trials
