Below Are a Few Questions From Your Upcoming PSI State Exam:

1. Given that an 80,000 Btu/h gas furnace will have the combustion air supplied from a mechanical air supply system outdoor source, the combustion air in shall be at least __ Cubic Feet per Minute of ventilation?

  • Correct Answer: IFGC – 304.9, CFM = (0.35 cu-ft/min/1,000 BTU/h) x (80,000 Btu/h) = 0.35 cu-ft/min x 80 = 28 CFM. A short cut would be 80 x 0.35 = 28 CFM

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

  • Step_1: IMC – 1105.6.3.1(1), 0.5 cfm per sq-ft x 200 sq-ft = 100 CFM, or
  • Step_2: 20 cfm per person x 2 operators = 40 CFM.
  • Step_3: Design the minimum ventilation at the larger of the two solutions, therefore 100 CFM

3. If the compressor displacement is 10 cu-in, but the unit’s actual pump volume is only 6 cu-in, what is the pump’s calculated volumetric efficiency?

  • Correct Answer: MR&AC (Edition 21) – 51.2.1,  Volumetric Efficiency = (Actual Volume / Theoretical Volume) x 100 = (6 cu-in / 10 cu-in) x 100 = 60%
