The image above represents the mean free path. To calculate the mean free path, two essential parameters are needed and these parameters are Pipe Diameter (D) and Number of Molecules (m).
The formula for calculating mean free path:
λ = 1 / √(2)π.D²m
Where:
λ = Mean Free Path
D = Pipe Diameter
m = Number of Molecules
Let’s solve an example;
Find the mean free path when the pipe diameter is 35 and the number of molecules is 7.
This implies that;
D = Pipe Diameter = 35
m = Number of Molecules = 7
λ = 1 / √(2)π.D²m
That is, λ = 1 / √(2)π..(35)²(7)
λ = 1 / (4.442).(1225)(7)
λ = 1 / (4.442).(8575)
So, λ = 1 / 38097.721
λ = 0.0000262
Therefore, the mean free path is 0.0000262.
