Q1) Let's consider the following three reactors (perfectly mixed) connected through pipes where Q is the volumetric flow rate (m3/s) and c is the concentration of a chemical spice A(mg/m3). By performing a mass balance for each reactor using mass flow rate (Qc) in - mass flow rate out, three linear equations are given by: 500Q13C1+Q21C2=0200Q21C2Q23C2=0Q23C2+Q13C1Q3C3=0 Find the concentrations of reactor 1,2 and 3 using Gaussian elimination. Q13=20(m3/s),Q21=40(m3/s),Q23=10(m3/s), and Q3=10(m3/s)
