Gas in two containers connected by a small hole
Q: A container is divided into 2 parts by a partition containing a hole of radius r. Helium gas in the two parts is held at temperature T1 = 75K and T2 = 300K respectively. After the system reaches a steady state, the mean free paths on each side are lambda1 and lambda2. What is the ratio lambda1/lambda2 when
(a) r>>lambda1 and r>>lambda2,
(b) r<
