Where β and q are given by eqs. (13.89) and (13.90). superscripts are here omitted because all calculations are for a vapor phase. the mixing rules most commonly used with the redlich/kwong equation for parameters a(t) and b are given by eqs. (13.91) through (13.93). for a binary mixture they become:

Water at 70°f and streams enter the mixing chamber at the same mass flow rate, determine the temperature and the quality of the exiting stream. 0 psia is heated in a chamber by mixing it with saturated water vapor at 20 psia. if both streams enters the mixing chamber at the same mass flow rate, determine the temperature and the quality of the existing system.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?
