The Knudsen number, Kn mfp/L, is a dimensionless parameter

Chapter , Problem 3.176

(choose chapter or problem)

The Knudsen number, Kn mfp/L, is a dimensionless parameter used to describe potential micro- or nanoscale effects. Derive an expression for the ratio of the thermal resistance due to moleculesurface collisions to the thermal resistance associated with moleculemolecule collisions, Rt,ms/Rt,mm, in terms of the Knudsen number, the thermal accommodation coefficient t, and the ratio of specific heats , for an ideal gas. Plot the critical Knudsen number, Kncrit, that is associated with Rt,ms/Rt,mm 0.01 versus t , for 1.4 and 1.67 (corresponding to air and helium, respectively). 3.1
