Question 497 Deck General

The correct answer is D) 82%. To determine the relative humidity given the dry bulb and wet bulb temperatures, we can use a psychrometric chart or a formula. In this case, with a dry bulb temperature of 55°F (13°C) and a wet bulb temperature of 50°F (10°C), the relative humidity is approximately 82%. The other options are incorrect because they do not accurately reflect the relative humidity based on the provided temperatures. Option A) 55% is too low, option B) 70% is too low, and option C) 75% is also too low for the given conditions.
