2. A well-mixed vessel of volume, V = 50 m³, is half-filled with acetic acid solution at a concentration of Co (20 kg/m³). Pure water is fed at a steady flow rate of Qo (5.0 m³/h) into the vessel and the well-mixed solution is pumped from the vessel at the same rate. The concentration of salt in the exit fluid C(t) kg/m³, is monitored. Derive the unsteady state differential material balance for the concentration of salt in the exit stream flowing from the vessel and show that it follows the following exponential relationship: open st C(t) = Coexp (20) V/2 [25%] artolizsup b. Determine the concentration of acetic acid present in the fluid in the intent vessel after a period of 10 hours. [10% ] A noitesup A relationship mots on [30%] nepobyl [30%] c. If the inlet flow rate had been 7.5 m³/h and the exit flow was maintained at 5 m³/h, derive the unsteady state mass balance for this case. d. Determine the volume of solution in the vessel after 10 hours and the concentration of the acetic acid in the stream leaving the vessel. [5%] e. What would you need to do after the 10 hour mark has been reached in d?
