Using the available references, if the dry bulb temperature is 84° and the wet bulb temperature is 81°, what is the relative humidity in a cargo hold?

A 71%
B 79%
C 81%
D 88%
AI Explanation

The correct answer is D) 88%. To determine the relative humidity given the dry bulb and wet bulb temperatures, we can use a psychrometric chart or a formula. Based on the information provided, with a dry bulb temperature of 84°F and a wet bulb temperature of 81°F, the relative humidity is approximately 88%. The other options are incorrect because they do not accurately reflect the relative humidity for the given temperatures. Option A) 71% and Option B) 79% are too low, while Option C) 81% is slightly lower than the correct answer of 88%.
