    Rocket Nozzle with combined equilibrium/frozen flow

    Homework Statement I am using the NASA CEA code to generate Isp and thrust data for the SSME. I solve the problem twice, once with a frozen flow condition and a second time with an equilibrium flow condition. However, there is a third request for solving the problem with equilibrium flow from...

    Methane mixed with air at 16:1 by mass

    No, the problem statement does not specify whether or not the mixture is in combustion or not. It simply states it is a mixture. I'm not sure how that changes the problem though? EDIT: Wait, I think I see what you're saying now. I'm trying to work as a combustion problem and it's actually just...

    Temperature inside a box as particles escape a small hole

    Homework Statement Edit: Thanks to gneill for showing me the LaTeX ropes. Equations should work now. A perfect gas enclosed within a container escapes into vacuum through a small circular hole. The particle flux through the hole is ##\frac{nc}{4}## and the energy per particle escaping can be...

    Fraction of molecules have kinetic energy of 1/2mC^2

    Homework Statement Consider a gas of molecules of mass m at equilibrium at temperature T. Obtain an expression for the fraction of molecules having kinetic energy e = 1/2mC2 in the range e to e + de. This is problem 5.3, page 48 of Vincenti and Kruger's Intro to Physical Gas Dynamics Homework...
