The flowchart for the absorber involves seven unknown variables (ṁ₀ and ṁ_Cl2 having been determined in Problem 12.5). Write the seven equations you would use to calculate those variables, noting that the amounts of chlorine and water in the head space are constant and so do not enter into steadystate material balances. Then solve the equations. Trial-and-error will be required as part of the solution. An equation-solving program or spreadsheet is a convenient tool for performing the required calculations.

This problem deal with the chlorine absorber, depicted in the following flowchart.
