Question

According to tanks in series model, the spread of the tracer curve is proportional to ____

(a) Square of distance from the tracer origin

(b) Square root of distance from the tracer origin

(c) Cube of distance from the tracer origin

(d) Inverse square of distance from the tracer origin

The question was asked in a job interview.

My question comes from Tanks in Series Model in chapter Compartment Models, Models for Non Ideal Reactors of Chemical Reaction Engineering

Answer 1

Right choice is (b) Square root of distance from the tracer origin

To explain: \(σ_{tracer \, curve}^2\) α Distance from point of origin

Spread of the curve α \(\sqrt{Distance \, from \, origin}. \)
