x kg/s of moist air at 35°C dry bulb temperature and 20% RH is mixed with kg/s of moist air at 20°C and a humidity ratio of 0.015 kg/kgDA in an adiabatic mixing chamber. The temperature of the air after mixing is 30°C. Find the humidity ratio of air after mixing. Post mixing, a sensible heating load of 4kW is supplied to heat up the mixed air. Calculate the final temperature of mixed air at the heater. Assume the barometric pressure to be 101.325 kPa. Use Cpm = 1.005 kJ/kg.K. Psychrometric chart is not required.
