3. 1kg or wood chips that have 10%wt/wt water have to be dried completely. Air at 51C dry bulb temperature and 10% relative humidity enters the dryer at a flow rate of 10L/ hour. The factory manager measured the temperature of the output air to be 30C. No heat is supplied to or removed from the drier, and the pressure is maintained constant at 1atm. (50 points) a. Explain why the output air is cooler even though no heat was removed from the system. b. Mark the input and output states of the air in the psychrometry chart and the path taken by any intermediate states. c. Systematically proceed to solve the mass and energy balance problem as discussed in class to Calculate the amount of water removed/hour from the drier and the time required for completely drying the wood chips. d. Calculate the enthalpy/hour and volumetric flow rate of the exiting air stream. e. At what temperature would the exiting air start fogging if cooled at constant pressure
