Problem 4- A HVAC system is operating in heating mode with a steam humidification system, as shown below. Air enters the system at 10°C and 70% relative humidity at a rate of 35m3/min. After heating and subsequent humidification by saturated water vapor at 100°C, the air leaves the system at 20°C and 60% relative humidity. Find (1) the temperature and relative humidity of the air when it leaves the heating section, (2) the heat transferred to the air in the...

6. Problem 3 (20 points): A Steam in a heating system flows through tubes whose outer diameter is 3 cm and whose walls are maintained at a temperature of 120°C. Circular aluminum alloy fins (k = 180 W/m.) of outer diameter 6 cm and constant thickness t 2 mm are attached to the tube, as shown in the figure below. The space between the fins is 3 mm, and thus there are 200 fins per meter length of the tube....
