P16-12, An RTD analysis was carried out on a liquid-phase reactor (Chem. Eng. J. 1,76 (1970)]. Analyze the following data: 0 150 175 200 225 240 250 t(s) CX 10' (g/m) 0 0 1 3 7.4 9.4 9.7 - t(s) 275 300 325 350 375 400 450 CX 10 (g/m2) 8.2 5.0 2.5 1.2 0.5 0.2 0 (a) Plot the E(1) curve for these data. (b) What fraction of the material spends between 230 and 270 seconds in the reactor? (c) Plot the F(t) curve for these data. (d) What fraction of the material spends less than 250 seconds in the reactor? (e) What is the mean residence time? (f) What is the variance o?? (g) Plot E(O) and FO) as a function of . nimede lleinoneontive sten tracer innut, Cholette and Cloutier Can. J
