To determine the enthalpy of air at a specific temperature and relative humidity, one must reference psychrometric charts or calculators that provide this information based on the defined parameters. In this scenario, air that is 50% relative humidity (RH) at a temperature of 95°F (35°C) has been calculated or sourced to have an enthalpy of 42.5 BTU/lb.

Enthalpy (measured in BTU/lb) in the context of air is a measure of the total heat content of the air, which includes both the sensible heat (related to the temperature of the air) and the latent heat (related to the moisture content). Since the air is at a warm temperature and contains a significant amount of moisture at 50% RH, its total heat content reflects both aspects effectively.

Air at different combinations of temperature and relative humidity will yield varying enthalpy values, which is why understanding the psychrometric properties of air is vital for professionals dealing with commercial drying, HVAC, and other related fields. In practical applications, knowing how to read these values helps technicians assess the amount of energy needed for effective drying, heating, or cooling operations.

Thus, the enthalpy of 42.
