That is true. I just needed to numerically prove what temperature pressure relations auto ignition could happen at even though our temps would be no where close. they wanted to see it on paper, but I found what i needed in a combustion physics book but thank you so much for the input!
This paper is helpful but I am trying to figure out how much pressure needs to be applied to autoignite, not how much pressure is released when it is ignited by a spark. That seems like the concept of that paper.
The problem is I am going to have to pipes coming into a T. Compressed in one...
The LEL is the leanest mixture in which it will still be flammable, which I believe for methane air the explosive limts are 5-15% so 5% would be the LEL?
Homework Statement
I want to figure out what pressure would need to be applied onto a 5% methane 95% air mixture to heat it up to the autoignition temp of 853 K.
