The calculator will show the saturation mixing ratio in grams of water per kilogram of dry air of a given temperature if the dry and wet bulb temperatures are set to the same value. Enter dry-bulb and wet-bulb temperature of the air and click the button to calculate relative humidity.

Enter dry bulb temperature plus either wet bulb temp RH or dewpoint temp. Determine the wet-bulb and dewpoint temperature the given temperature is 40C relative humidity is 50 and then actual station pressure is 3 millibars. Rain and Snow in the Northwest and Along the Eastern Seaboard. Acceleration Calculator Belt Length Calculator BMEP Calculator Brake Mean Effective Pressure Calculator.

Stull 2011 equation 341. Wet Bulb Temperature is calculated based on R. Twet 2377Log e wet6. The humidity calculator calculator finds the water vapor pressure e in the gas from the wet-bulb temperature tw the gas temperature t the gas pressure P and equilibrium vapor pressure e at tw using the following equation.

If partly saturated air is cooled without changing its pressure or amount of water vapor a point is reached when it becomes saturated. How to Calculate Dewpoint and Wet Bulb Temperature - Tutorial. Relative Humidity Dewpoint temp C. Calculate approximate wet-bulb temperature twet from approximated wet-bulb vapor pressure.
