What is the Dry Bulb Temperature when the Wet Bulb Temperature is 75°F and the Relative Humidity is 100%?

When the Wet Bulb Temperature is at 75°F and the Relative Humidity is 100%, it indicates that the air is saturated with moisture. At 100% relative humidity, the Dry Bulb Temperature, which measures the air temperature without considering moisture, matches the Wet Bulb Temperature because the air cannot hold any more moisture at this point.

In such conditions, the Dry Bulb Temperature must equal the Wet Bulb Temperature. Therefore, when the Wet Bulb is 75°F under these circumstances, the Dry Bulb Temperature is also 75°F. This is a fundamental principle in thermodynamics related to humidity and temperature readings, confirming that under saturated conditions, both temperatures converge at the same value.
