Psychrometric chart wet bulb
WebA psychrometric chart is a graph of the thermodynamic parameters of moist air at a constant pressure, often equated to an elevation relative to sea level. The ASHRAE-style … WebThe properties of moist air are readily shown in a psychrometric chart as in Fig. 1. A psychrometric chart shows the inter-relationship between dry bulb temperature, wet bulb temperature and the humidity ratio. It also shows the relative humidity, the dew point temperature and sometimes the enthalpy of the mixture and the specific volume.
