1. (20%) Given the inlet and exit conditions to an air conditioner shown below. For MUSTAFa the conditions shown, what heat transfer to the cooling fluid is required per kg dry air flowing through the device? If the volume flow rate of the inlet atmospheric air is 200 m³/min, determine the dry air flow rate. Show all work. In the proper manner, clearly define the system you are using. Only an analytical solution is permitted. (The solution using Psychrometric chart is not acceptable!) Atmospheri e Air Ti=30°C Pi=85 kPa 1-80% P=200m³/min Cooling fluid In Out Insulated Flow Duct T-20°C P-83 kPa Condensate At 20°C 2-95%
