I need parts e though h please
(20 points) Condensation Follow the standard energy balance steps to determine the water condensed and the heat removed from a humid air stream. The feed stream contains 15 wt% water (balance is air), has a temperature of 200C and a pressure of 1 atm. The exit gas stream is at 1 atm and 30C. The exit vapor composition should be determined from the psychrometric chart (saturated). The heat of vaporization of water at 30C 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. f. Construct and fill out enthalpy table. Define variables for unknown enthalpies. Species/Phase min (kg/s) Ain (kJ/mol) mout (kg/s) Out (kJ/mol) H20 (v) Air (g) H20 (1) g. Determine unknown enthalpies. h. Determine 0.
