Question

The flow through a reactor is 10 L/min. A pulse test gave the following [tracer] concentration

measurements at the outlet:

        t (min) :     0       0.4      1.0        2         3         4         5         6         8       10

        C x 10⁵ :    0      329     622     812     831     785     720     650     523     418

               t :         15       20       25       30       35       40       45       50       60

               C :       238     136      77       44       25       14        8         5         1

a) Plot the Residence Time Distribution (RTD) function, E(t), as a function of time.

b) Plot the Cumulative Distribution (CTD) function, F(t), as a function of time.

c)   What are the mean residence time (?_m) and the variance (?²) ?

h) What is the reactor volume?
