A and B containers (fixed volume) are connected together by a valve. Tank A contains 400 kPa and 0.3 m3 refrigerant 134a at 60% dryness. Tank B contains 0.5 m3 of refrigerant 134a at 240 kPa pressure and 100 oC temperature. Then the valve is opened and the system reaches 280 kPa equilibrium pressure. Calculate the final temperature.

Air at 620 kPa and 500 K enters an adiabatic nozzle that has an inlet-to-exit area ratio of 2:1 with a velocity of 120 m/s and leaves with a velocity of 380 m/s. The enthalpy of air at the inlet temperature of 500 K is h=503.02 kJ/kg Determine the exit pressure of the air. The exit pressure of the air is -652.73 kPa.
An air conditioned mall with a capacity of 1500 persons is to be maintained at 250C db temperature and 58% RH. The sensible and latent heat loads are 120 KW and 50 KW, respectively. The conditioned air enters the mall at 190C. For proper ventilation, 45% of the supply air is fresh air and the rest is recirculated air. Outside air is at 350C and 50% RH. Determine (a) the volume flow rate of recirculated air, (b) the apparatus dew point, and (c) the refrigeration load.
