Psychrometer is an application to calculate the various properties of moist air. You can easily calculate values such as dew point temperature and relative humidity. To calculate the water vapor pressure, we use the Tetens(1930) equation.
- Intuitive operation of slider.
- Temperature units, Celsius (℃) and Fahrenheit (℉).
- Volumetric humidity units, (g/m³) and (gr/ft³).
- Specific humidity units, (g/kg) and (gr/lb).
- Pressure units, (hPa), (mmHg) and (inHg).
- Enthalpy units, (kJ/kg) and (Btu/lb) .
- Specific volume units, (m³/kg) and (ft³/lb).
- There are two types of psychrometers, natural and forced ventilation.
The value can be computed:
Relative humidity, Discomfort index, Volumetric humidity, Specific humidity, Vapor pressure, Saturation vapor pressure, Dew point temperature, Enthalpy, Specific volume.
