4.30 Refrigerant 134a enters a heat exchanger operating ai steady state as a superheated vapour at 10 bars. 60°C. where it is cooled and condensed to saturated liquid at 10 bars. The mass flow rate of the refrigerant is 10 kg/min. A separate stream of air enters the heat exchanger at 37°C with a mass flow rate of 80 kg/min. Ignoring heat transfer from the outside of the heat exchanger and neglecting kinetic and potential energy effects, determine the exit air temperature, in °C.

Q1: An engineer claimed that his device produces two streams of 1 am air (outlet 1) and 1.5 atm (outlet 2) at temperatures of 460 °R and 635 °R, respectively, if he enters 530 °R of the air at 5.1 atm. If the ratio of outlet 2 to outlet 1 is 0.6, justify the engineer's claim. Assume ideal gas process with a constant heat capacity of 0.24 Btu/lb.°R.
