All About Engineering


is the science of studying the thermodynamic properties of moist air and the use of these properties to analyze conditions and processes involving moist air.

Moist air is a mixture of dry air and water vapour. In atmospheric air, water vapour content varies from 0 to 3% by mass.

-Is often used in the design of refrigerating system by engineers to determine properties of moist air by plotting in a Psychrometric Chart
