The volumetric flow rate of the first of the two airflows at 293 K is 1 m3 /s, the other is 2 m3 /s at 473 K, and both have a pressure of 100 kPa. The two streams are mixed without any heat transfer and an output stream of 100 kPa pressure is obtained. Determine the temperature and volumetric flow rate values of the outlet stream, ignoring the kinetic and potential energy changes. Assume that air behaves as an ideal gas.
