Cunningham slip factor
WebApr 10, 2024 · The mean free path of particles of a gas equation is mentioned-below: λ = k * T / (√2 * π * d² * p) Where, λ is the mean free path. k is the Boltzmann constant i.e k = 1.380649 x 10 -23 J/K. T is the temperature of the gas. d is the diameter of the particle. p is the pressure of the gas. The mean free path formula requires atomic diameter ... WebThe Davies parameterization gives a Cunningham slip correction factor that is, on average, 2.5% larger than the other parameterizations over the diameter range 50 − 500 nm that is relevant to our work, and the retrieved effective densities using the Davies parametrization are approximately 0.3% less than the values calculated using the other ...
