Question 323 Deck General

The correct answer is C) 85%. To determine the relative humidity given the dry bulb and wet bulb temperatures, we can use a psychrometric chart or table. With a dry bulb temperature of 68°F and a wet bulb temperature of 65°F, the corresponding relative humidity is approximately 85%. The other answer choices are incorrect because: A) 66% is too low for the given temperatures. B) 74% is also too low. D) 90% is slightly higher than the actual relative humidity of 85%.
