Mean Free Path using Number Density Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mean Free Path of Molecule = 1/(Number Density*pi*Distance Between Two Bodies^2)
λ = 1/(n*pi*d^2)
This formula uses 1 Constants, 3 Variables

Constants Used

pi - Archimedes' constant Value Taken As 3.14159265358979323846264338327950288

Variables Used

Mean Free Path of Molecule - (Measured in Meter) - The Mean Free Path of Molecule is the average distance an object will move between collisions.
Number Density - (Measured in 1 per Cubic Meter) - Number Density is the moles of particles per unit volume.
Distance Between Two Bodies - (Measured in Meter) - Distance Between Two Bodies is the measurement of how far two bodies are placed.

STEP 1: Convert Input(s) to Base Unit

Number Density: 9.89873 1 per Cubic Meter --> 9.89873 1 per Cubic Meter No Conversion Required
Distance Between Two Bodies: 12 Meter --> 12 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

λ = 1/(n*pi*d^2) --> 1/(9.89873*pi*12^2)

Evaluating ... ...

λ = 0.000223309992364755

STEP 3: Convert Result to Output's Unit

0.000223309992364755 Meter --> No Conversion Required
