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

Hint:

More tanks → smoother response; spread grows slower than linearly.

Answer 1

The Correct Option is B

In tanks-in-series model, the variance \( \sigma^2 \propto N \).
Spread grows as square root of distance/time from origin.
