A compressor specification in this exercise limits suction-gas temperature to 65°F at the stated operating condition. The measured temperature is 72°F. How far above the stated limit is it?
- 7°F
- B37°F
- C65°F
- D137°F
Where to look it up
Explicit exercise assumptions; not a universal code requirement.
Why A is correct
72 − 65 = 7°F. Apply the equipment-specific limit supplied here; do not substitute a universal 40°F return-gas maximum.
