Following is a labeled flowchart for a steady-state two-unit process, with boundaries shown to denote subsystems about which balances can be taken. State the maximum number of balances that can be written for each subsystem and the order in which you would write balances to determine the unknown process variables. (See Example 4.4-1.) | 200 g C/s 475 g/s x(g A/g) y(g B/g) z(g C/g) 800 g/s m,(g/s) m(g/s) UNIT UNIT 0.200 g A/g 0.800 g B/g (8 A/g) (1 -x)(g B/g) A/g) y2(g B/g) (1-x2-y)(g C/g) 0.012 g A/g 0.558 g B/g 0.430 g C/g 100 g A/s
