Question 498Deck General70% to pass
Using the available references, if the dry bulb temperature is 77° and the wet bulb temperature is 69°, what is the relative humidity in a cargo hold?
AI Explanation
The correct answer is A) 67%.
To determine the relative humidity given the dry bulb and wet bulb temperatures, we can use a psychrometric chart or table. Based on the provided dry bulb temperature of 77°F and wet bulb temperature of 69°F, the relative humidity is approximately 67%.
The other options are incorrect because:
B) 70% is slightly higher than the actual relative humidity of 67%.
C) 77% is too high and would correspond to a lower wet bulb temperature.
D) 81% is also too high and does not match the given dry and wet bulb temperatures.
