Two moist inlet air streams are mixed adiabatically. This Demonstration uses mass and energy balance equations to determine the outlet air stream. You can set the dry-bulb and wet-bulb temperatures of the first inlet stream and the dry-bulb temperature and relative humidity of the second inlet stream. You can change the values of the volumetric flow rates of the inlet air streams. The "psychrometric data" button shows a chart with all the relevant thermal parameters for the two inlet air streams and the outlet air stream. "DA" refers to dry air. The data includes the dry-bulb, wet-bulb and dew point temperatures expressed in , the relative humidity in , the absolute humidity or moisture content in , the humid volume in and the specific enthalpy in .
