In Propep, it seems that whenever I inject a lot of water into the
combustion and let the resulting products expand to near vacuum, the
end temperature is ridiculously low.
Is this a bug in Propep? |

I'm not familiar with Propep, but when you say "expand to near vacuum"
it sounds like a ridiculously low temperature is what you should
expect. pV=nRT.
