[領域]氣體動力論 [題目] 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. [瓶頸] 這一題條件給的很少, 想運入射頻度的想法下去解,但又不知道給的小孔逕 的直徑的條件是要怎麼用? 希望版上的的高手們幫解惑,謝謝^^ -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.114.213.121
