Psychrometric Properties: STD ATM
61.0 100 to 70.0 100
Psychrometric properties of moist air — humidity ratio, enthalpy, dew point, wet-bulb temperature, and specific volume as functions of dry-bulb temperature and relative humidity; also includes saturation thermodynamic and transport properties (viscosity, thermal conductivity, Prandtl number, density) from ASHRAE 2021 tabulated data
