The formula to calculate the Mixed Air Temperature (Tm) is:
\[ \text{Tm} = \text{To} \times \%OA + \text{Tr} \times \%RA \]
Where:
Mixed air temperature is defined as the temperature of two different temperature bodies of air after they have reached equilibrium.
Let's consider an example:
Using the formula to calculate the Mixed Air Temperature:
\[ \text{Tm} = 30 \times 0.40 + 20 \times 0.60 = 12 + 12 = 24 \, \text{°C} \]
This demonstrates that with the given conditions, the mixed air temperature would be 24 °C.
