About This Calculator
This calculator estimates the wet bulb temperature based on dry bulb temperature and relative humidity using the Stull empirical formula. It's suitable for quick meteorological and HVAC-related calculations.
How It Works
The calculator applies the Stull formula: Tw = T × atan(0.151977 × sqrt(RH + 8.313659)) + atan(T + RH) - atan(RH - 1.676331) + 0.00391838 × RH^(3/2) × atan(0.023101 × RH) - 4.686035, where T is the dry bulb temperature in Celsius and RH is the relative humidity in percent.
Frequently Asked Questions
What is wet bulb temperature?
It's the lowest temperature air can reach through evaporative cooling. It reflects how effectively sweat or water can evaporate.
Why is it important?
Wet bulb temperature is crucial in meteorology, climate safety, agriculture, and industrial cooling systems.
What are the limits of this calculator?
This tool is accurate for dry bulb temperatures between -50°C and 60°C and relative humidity from 0% to 100%.
