[领域]气体动力论
[题目] Given two chambers connected by an orfice of such size that MFP>>d
(MFP = mean free path, d = orfice diameter ), let the temperature
of one chamber be T1 and the other one be T2. Derive an expression
for the pressure ratio P1/P2 between the two chambers.
[瓶颈] 这一题条件给的很少, 想运入射频度的想法下去解,但又不知道给的小孔迳
的直径的条件是要怎麽用? 希望版上的的高手们帮解惑,谢谢^^
