Psychrometrics for Fan Systems

Psychrometrics is the study of the properties of mixtures of air and water vapor. A general knowledge of psychrometrics is very useful in fan application engineering, mainly because the performance of the fan is directly related to the density of the gas. Knowledge of psychrometric principles allows the fan application engineer to measure the amount of water vapor in the air, determine the density of the mixture, and thus accurately predict changes in fan performance. In this self-guided course, you will graphically explore psychrometric properties, such as dry bulb, wet-bulb, relative humidity, dew point, and humidity ratio as they are plotted on the psychrometric chart. Your knowledge of these properties will allow you to accurately calculate density and give you other skills useful in fan application engineering, such as the ability to predict whether condensation will occur in the system.
