Incoming air flow of 200 m3/h at a temperature of 20oC and a humidity ratio of 0.012 kgv/kga is mixed in a chamber with another incoming air flow of 500 m3/h at a temperature of 15oC and a humidity ratio of 0.008 kgv/kga. Based on the corresponding mass flow rates (not the original volumetric flow rates) determine:
a) The mass flow rate of the mixed air (i.e., the combination of the two flows) leaving the chamber in kg/s.
b) The temperature of the mixed air leaving the chamber.
Part (a) you will first need to find the density or specific volume for each incoming state.
