Hi I need asisstance with a thermo review problem, Thank you! A heat exchanger is used to heat air. The air enters at 300 K with a flow rate of 5 kg/s. The air is heated by a separate stream of H2O that enters the heat exchanger at 300 kPa, saturated vapor and leaves as saturated liquid. If the H2O flow rate is 0.2 kg/s, determine the exit temperature of the air (K). Cpair=1.027 kJ/kgK. Note the air and H2O areseparate streams. No mixing occurs.
