Moist air
Psychrometric Calculator
Calculate related moist-air properties from an identified dry-bulb temperature, relative humidity, and total pressure.
Calculation method
The calculator estimates vapor pressure from dry bulb and RH, then derives humidity ratio, dew point, and moist-air enthalpy. Wet bulb is solved by a constant-enthalpy approximation. Results depend on stated pressure; do not assume sea-level pressure at elevation.
Example
At 24°C, 50% RH, and 101.325 kPa, the tool reports related moist-air properties for that single state point.
Limits
This is a planning calculator over the stated input range. Use ASHRAE psychrometric methods, calibrated measurements, and project requirements for final work.
