1- The outflow concentration from a reactor is measured at a number of times over a 24-hr period: t, hr 5.5 10 12 14 16 18 20 24 C, mg/ 1.5 2.3 2.1 4 5 5.5 5 3 1.2 The flow rate for the outflow in m'/s can be computed with the following equation: Q(t) = 20 + 10 sin (t 10) 24 Use the best numerical integration method to determine the flow- weighted average concentration leaving the reactor over the 24-hr period, So Q(t)c(t)dt So Q(t)dt
