Streams of air and water vapor are mixed adiabatically. Both streams are at a pressure of 1 atm. You can set the values of the molar flow rate and temperature of the two streams.[more]
This Demonstration computes the outlet stream's temperature using the energy balance equation for nonreactive systems: .
The specific enthalpies of air and water are computed using the temperature-dependent expressions of the constant-pressure heat capacities given in [1, Appendix B2]. In addition, we chose these reference states: air (gas) and water (vapor) both at 25 °C and 1 atm.
It is straightforward to extend this calculation to a larger number of streams and/or components.[less]
