Question

what is the relative humidity when the dry - bulb temperature is 16°c and the wet - bulb temperature is 14°c?
90%
14%
80%
13%

Explanation:

To determine relative humidity from dry - bulb (16°C) and wet - bulb (14°C) temperatures, we can use a psychrometric chart or recall humidity relationships. The difference between dry - bulb and wet - bulb temperature (the wet - bulb depression) here is \(16 - 14=2^{\circ}\text{C}\). Using psychrometric principles or reference tables, when dry - bulb is 16°C and wet - bulb depression is 2°C, the relative humidity is 90%. The other options (14%, 80%, 13%) do not match the expected value from humidity calculations for these temperatures.

Answer:

A. 90%
