Internal friction of gases (viscosity of gases)

The task:

Measure the viscosity of H₂, CO₂ and O₂ at 20 °C and at 70 °C. Determine the mean free path and the collision cross section of those gases.

What one should know:

Basics of the kinetic gas theory, transport properties of perfect gases, Newtonian fluids, laminar flow, 1. Fick’s law.
