Define Hole in Wall (Princeton)?
A container is separated into two parts I and II by a partition with a small hole of diameter d Helium gas in the two parts is held at temperatures T1 = 150 K and T2 = 300 K respectively, through heating of the walls.
a) How does the diameter d actuate the physical process by which the Gases come to steady state?
b) What is the ratio of the signify free paths λ1/λ2 between the two parts when d <<λ1 <<λ2?
c) What is the ratio when d >>λ1>>λ2?
