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 is used, others the 'change' in temp is used. I can't tell when or why the difference!
