In a steady-state flow process carried out at atmospheric pressure, 1 mol/s
o air at 600K is continuously mixed with 2 mol/s of air at 450 K. The
product stream is at 400 K and 1 atm. A schematic representation of the
process is shown below. Determine the rate of heat transfer and the rate
of entropy generation for the process. Assume the ideal -gas state for air
with Cp(id) = (7/2)R, that the surroundings are at 300 K, and that kinetic -
and potential- energy changes are negligible.
