The volumetric flow rate through a reactor is 10 dm³/min. A pulse test gave the following concentration measurements at the outlet:

a. Plot the external-age distribution E(t) as a function of time.
b. Plot the external-age cumulative distribution F(t) as a function of time.
c. What are the mean residence time tm and the variance, σ²?
d. What fraction of the material spends between 2 and 4 minutes in the reactor?
e. What fraction of the material spends longer than 6 minutes in the reactor?
f. What fraction of the material spends less than 3 minutes in the reactor?
g. Plot the normalized distributions E(Θ) and F(Θ) as a function of Θ.
h. What is the reactor volume?
i Plot the internal-age distribution I(t) as a function of time.
j. What is the mean internal age αm?
