Problem 1: 89 Five reactors linked by pipes are shown in Fig. 8.9. The rate of mass flow through each pipe is computed as the product of flow (Q) and concentration (C). At steady state, the mass flow into and out of each reactor must be equal. For example, for the first reactor, a mass balance can be written as Qon ou + Q3143 = 2156 + 1241 Write mass balances for the remaining reactor and express the equations in the matrix form. Use gauss elimination for the concentrations in each reactor. Qis - 5 Ose-2 225 6 12 Qu-9 Coi 20 es - 2 lue - 6 ls - 3 los 7 03-50 FIGURE P8.9
