Is there a way you can calculate exhaust flow using intake flow and exhaust temp? Maybe I would need fuel quantity as well. I just need a rough idea.. It's for on a diesel.
The chemical composition changes, too.the air is just heated way up so the only thing that changes is pressure right?
The number of moles can change, but density has to stay the same (if the volume is constant).Density stays the same since the moles of air in there is the same as before
Average of what?But I guess the exhaust gas temp is an average temp and would work.
Okay.Average temp of the gas flowing out of the engine.
Diesel is mainly a source of carbon and hydrogen, and hydrogen reacts as ##O_2 + 4 H \to 2 H_2 O##, so you get an additional molecule. ##O_2 + C \to CO_2## does not change the number of molecules. Each diesel molecule gives several of those reactions before it is gone.How does the number of moles change? I realize the diesel adds some but does it add a significant amount?
