QUESTION 5 (P01, CO3, C1, C5, C5, C6, C1) A tank with maximum capacity of 100 liter is used to dilute copper sulphate solution (A). The tank is initially filled with 50% of the maximum volume of 0.025 kg/liter of A. A stream of distilled water enters the tank at the flowrate of 0.6 liter/min. The tank is perfectly mixed and the outlet streams is discharged at a rate of 0.5 liter/min. a) Draw and completely label the process flow. (3 marks) b) Derive differential material balance equations for the total mass and component (copper sulphate). Provide the initial conditions. (10 marks) c) Derive the expression of volume with time. (4 marks) d) Sketch expected trend for the volume of the solution with time. (3 marks) e) Determine the time taken for the solution to reach its maximum volume before overflows. (2 marks)
