Specific enthalpy psychrometric chart
WebChanges in the total energy possessed by an air sample are known as changes in the enthalpy of the air sample and consist of the sum of the sensible and latent heat changes. The properties of air can be shown on a single graph known as a psychrometric chart. Figure 1 illustrates such a chart. WebAt the inlet point 1, there is a mixture of dry air and water vapor; therefore, the specific enthalpy can be obtained from the psychometric chart or it can be calculated as follows: …
