Question 1 Five reactors linked by pipes are shown in the figure below. 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: Qo1C01 +Q31C3 = Q15C1 + Q12C1 a) Clearly develop the system of equations that describes the steady-state operation of the reactors. Using MATLAB, determine the matrix inverse of the system, rounding the final answers to four decimal places. b) Use the matrix inverse to determine the concentration in reactor 5 if the inflow concentrations are changed to Coi = 30 and Co3 = 40. Round the final answer to three decimal places. Qis = 3 lss = 2 Qs. = 2 Q25 = 1 loi = 5 Q12=3 l24 = 1 l. = 11 Con = 20 Q23 = 1 934 =8 Q31 = 1 = 8 Co3 = 50
