Chapter 7, Problem 7.6P

Interpretation Introduction

Interpretation: The viscosity of oxygen needs to be determined at a particular temperature. The calculated value needs to be compared with the value present in Appendix.

Concept introduction Viscosity is the resistance to flow and are given by the following relation,

  $\text{μ}\text{=}\text{2}{\text{.6693×10}}^{\text{-6}}\left(\frac{\sqrt{\text{MT}}}{{\text{σ}}^{\text{2}}{\text{Ω}}_{\text{u}}}\right)$   ............ (1)

Here,

  $\text{μ}$ is the viscosity of pure gas.

M is the molecular weight of the gas

T is the temperature of the gas in Kelvin

  $\text{σ}$ is the collision diameter of the gas in Angstrom and is Lennard Jones parameter.

Also, ${\text{Ω}}_{\text{u}}$ is the collision integral and is a Lennard Jones parameter that varies with the $\frac{\text{kT}}{\text{ε}}$ , Where k is the Boltzmann constant and $\text{ε}$ is the characterization energy.
