Question

If C=2 and area under the C – curve is 4 for a pulse input, then the value of E is ____

(a) 2

(b) 0.5

(c) 1

(d) 8

I got this question in an interview for internship.

My enquiry is from Non Ideal Flow Basics topic in section Fluid-Fluid Reactions: Kinetics & Basics of Non Ideal Flow of Chemical Reaction Engineering

Answer 1

Correct choice is (b) 0.5

To explain: E = \(\frac{C}{\int_0^∞ C dt} \)

\(\int_0^∞\) C dt is the area under the C – curve. Hence, E = \(\frac{2}{4}\) = 0.5.
