Psychrometrics humidity
Webtemperature and 80% relative humidity to a dry bulb temperature of 80 C. Solution 1. Using the psychrometric chart, we find at 30 C dry bulb temperature and 80% relative humidity, the enthalpy H1 = 85.2 kJ/kg dry air, humidity ratio W1 = 0.0215 kg water/kg dry air, and specific volume V1= 0.89 m3 /kg dry air. WebThe user then enters a desired Dry Bulb temperature and one of three humiditymetrics: Relative Humidity , Wet Bulb temperature, or Dew Point temperature. At the end of the calculation, the user has the option to convert from the English to the SI (or vice versa) unit system. Common atmospheric pressure values are:
