I'm not sure what you mean by 'defined' in both cases, the initial (combustion temp) was given, and exit was found and needed for other calculations. So for two different questions, of the same 'basic' principals (rocket combustion) to find exit velocity: for one problem, we used exit temp for...

I'm working on some propulsion homework for rockets. Basically combustion happens, and the gas velocity increases. sometimes we use: exhaust velocity = sqrt ( 2*Cp*exit temp) other times we use exhaust velocity = sqrt (2*Cp*(initial temp - final temp)) so the difference is, sometimes exit temp...
