3. An air conditioner draws 175 m³/min of humid air at atmospheric pressure, 37°C and 94% relative humidity. It cools and compresses the air to 10°C and 5 atm. Condensed water leaves the unit through a drain line. a. Draw the system flowchart. Solve the material balances to determine the flowrates and composition of the outlet liquid and vapor streams. a. Write the energy balance and cancel negligible terms. b. Choose a reference state phase, temperature, and pressure for each species. c. Construct a table with columns for inlet and outlet stream component flow rates (ni) and specific enthalpies (Ĥ₁ ) relative to reference states d. Draw an enthalpy path and label it for each Ĥ; in your table. Calculate Ĥ; and insert the values in table. e. Solve for AH. Solve the energy balance for the unknown AC duty ( Q + W₂) in kW.
