An adiabatic dehumidifier is used to extract excess moisture from the air inside your hostel room with dimension 8 x 6 x 3 m3 . The room was initially at a dry bulb temperature of 30 oC, 70 % relative humidity is to be humidified to 40 % relative humidity. a) Sketch the process in the phsychrometric chart provided b) Estimate the adiabatic saturation temperature of the entrance air and the final temperature (dry bulb) of the air. c) Calculate the amount moisture removed by the humidifier (in kg) d) Briefly explain how could you reduce the humidity further using the humidifier

9.77 Methane is burned with 25% excess air in a continuous adiabatic reactor. The methane enters the reactor at 25 C and 1.10 atm at a rate of 550 L/s, and the entering air is at 150 C and 1.1 atm. Combustion in the reactor is complete, and the reactor effluent gas emerges at 1.05 atm. a) Calculate the temperature and the degrees of superheat of the reactor effluent. (Consider water to be the only condensable species in the effluent)....

Solid desiccant air dehumidifier systems are widely used to supply dry air for many industrial processes. As humid atmospheric air flows through the system, the water vapor in the air is adsorbed by the desiccant material, resulting in dry air leaving the system. Inlet air velocity and tekperature are observed as predominant parameters that influence the outlet conditions of the air. Consider a cylindrical air channel with a length of 1 meter and an inner diameter of 20 mm, as...

Water is boiled in a cup and put to cool down inside a room. The air temperature in the room is increasing linearly according to the function Ta(t) = 22 + 0.015t (t in minutes, T in Celsius). Assume Newton’s Law of Cooling is satisfied: the rate of change of water temperature is proportional to the difference between the temperature of the water and the temperature of the environment. The temperature of the water was checked after 8 minutes and...
