How does the change in area affect the velocity of helium gas in a vacuum?

[QUOTE="ilc, post: 5478761, member: 442007"] Hi: Hi there, it appears I forgot to mention the system is under vacuum... and the outlet pressure of 0.065 psi is that of the vacuum chamber here is a better diagram: [URL]http://imgur.com/64b7WLT[/URL] We can assume vacuum extends upto the inlet Helium stream. This means density of Helium will change once it leaves the gas tank and that its compressible. As such, [B]it makes calculate the density (rho = P*MW/(RT)) at vacuum pressure, right ?[/B] With regards to your comment in 1): since i am assuming constant mass flow, couldn't i use rho*V*A between sections and work my way up to calculate the outlet velocity?
