Added a new subsection entitled "Velocity of gases exiting the rocket engine nozzle exhaust "

I added a new subsection ported from the WP article "Rocket nozzle" which I originally created when I was a Wikipedian. I slightly revised some of the text to fit into this article and I re-did many of the WP wiki links to be consistent with the pertinent CZ article titles. Milton Beychok 03:23, 22 March 2010 (UTC)

Combined "Specific impulse" and "Thrust" into one section

Howard, I combined the "Specific impulse" and "Thrust" sections into one section because the math for those two parameters flow together. Also added NASA website pages as references to document the math. If you disagree with what I did, please feel free to revise any or all of it. Milton Beychok 17:59, 25 March 2010 (UTC)
