Question

Follow the standard energy balance steps to determine the water condensed and the heat removed from a humid air stream. The feed stream contains 30 wt% water (balance is air), has a temperature of 250°C and a pressure of 1 atm. The exit gas stream is at 1 atm and 30°C. The exit vapor composition should be determined from the psychometric chart (saturated). The heat of vaporization of water at 30°C is 43.8 kJ/mol. a. Draw a picture and label appropriately (Basis: 1 kg/s feed). b. Perform a degree of freedom analysis. c. Write appropriate equations. d. Complete all material balances. e. Specify reference states. f. Construct and fill out t enthalpy table. Define variables for unknown enthalpies.

g. Determine unknown enthalpies. h. Determine Q. Please give your answer in kW.
