What is the relative humidity if the dry-bulb temperature is 8˚C and the difference between the wet and dry-bulb temperatures is 6˚C ?

39%

Explanation:

The Dry Bulb Temperature (also known as air temperature) is the ambient air temperature.

The Wet Bulb temperature is the temperature of adiabatic saturation.

The relative humidity is the amount of water vapor in the air. The relative humidity can be gotten from the dry bulb and wet bulb temperature. The difference between the wet bulb and dry bulb temperature as well as the dry bulb temperature is used to determine the relative humidity with the help of a Psychrometric Chart

Given that the dry-bulb temperature is 8˚C and the difference between the wet and dry-bulb temperatures is 6˚C. From the chart:

Relative humidity = 39%

39% I believe is correct.

lol for the pointsss
