Question 502 Deck General

The correct answer is A) 31%. To determine the relative humidity given the dry bulb and wet bulb temperatures, you can use a psychrometric chart or a relative humidity formula. Based on the information provided (dry bulb temperature of 76°F and wet bulb temperature of 58°F), the relative humidity in the cargo hold is approximately 31%. The other options are incorrect because they do not match the relative humidity calculation for the given temperatures. Option B) 47% and Option C) 61% are higher than the correct value, while Option D) 76% is significantly higher than the actual relative humidity.
