What is the enthalpy change of 20oC system if the heat capacity of air at 25oC is 5 J/oC and heat capacity of water vapor at 25oC is 10 J/oC, enthalpy of vaporization is 10 J, and the humidity is 20%?

Topics include: Humidity chart and its applications, energy balances using process simulators, degrees of freedom analysis and steady and unsteady state materials.

A psychrometric chart, also known as a hygrometry chart, is a graphical representation of the thermo-physical properties of a gaseous-vapor mixture. It's a tool that helps users understand the relationships between the various parameters of supply air and the relative humidity.
