Correct Answer: MR&AC – 51.2.1, Volumetric Efficiency = (Actual Volume / Theoretical Volume) x 100 = (6 cu-in / 10 cu-in) x 100 = 60%.

If the compressor displacement is 10 cu-in, but the unit’s actual pump volume is only 6 cu-in, what is the pumps calculated volumetric efficiency?.Step_3: Design the minimum ventilation at the larger 100 CFM.Step_2: 20 cfm per person x 2 operators = 40 CFM.

If two operators are performing “normal” technical maintenance of equipment inside a small 200 sq-ft room, what would be the required CFM?.
