Two streams of air mix together to form a single (third) stream. The first stream has 500 ft3/s of air entering at (600R, 50 psi). The second stream has 6 lbm/s of air entering at (800R, 14.696 psi). The air leaves at a pressure of 14.696 psi. Find the heat transfer and work, or rate of heat transfer and work for this process. Find the exit temperature of the third stream.
