Problem
Consider two states of atmospheric air: (1) 40oC, φ = 50% and (2) 25oC, T wet = 16oC. Suggest a system of devices that will allow air in a steady- flow process to change from (1) to (2) and from (2) to (1). Heaters, coolers, (de)humidifiers, liquid traps, and so on are available, and any liquid/solid flowing is assumed to be at the lowest temperature seen in the process. Find the specific and relative humidity for state 1 the dew point for state 2, and the heat transfer per kg dry air in each component in the system.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
