How to calculate dry bulb temperature

Web16 feb. 2024 · Temperature at which saturated vapour pressure is 24 mb = 21°C, = dewpoint. If you do want to put it on XL, saturated vapour pressure as function of temperature (°C) is given to a good approximation by P v = A*e (B*T/ (T+C)) where A = 6.105 mb, B = 17.074, C = 234.011. Multiply by the RH to get the actual pressure of the … WebThe wet-bulb temperature is always between the dew point and the dry-bulb temperature (T d ≤ T w ≤ T). This can be implemented on thermodynamic diagrams, such as the Skew-T log P, which is discussed in more detail in the next chapter. Take note of this description for later. To find the wet-bulb temperature on a Skew-T log P diagram, follow ...
