@MetalStorm I think the "@" symbol is required to notify users, so I'm not sure if you've seen Chet Miller's latest message then...

Hello, yes I saw it.. it seems that he agrees with me
Could you find a book where it says that the equation is valid for irreversible process? I think that would be helpful
*processes
I searched many of them, but didn't find anything
It seems you are very interested in this. We could also email some of the authors of the books and ask them this question, the email would be rather short, so there is some chance

@MetalStorm Actually he agrees with me -- read his answer closely. He just said that it is possible (even if difficult) to make an irreversible isobaric process have $\Delta H = Q$
@MetalStorm In his example, there is an irreversible heat flux imposed -- hence making the process irreversible. We also have $P_{int} = P_{ext} = $ constant in his answer too. So, therefore, an irreversible isobaric process with $\Delta H = Q$, exactly what you were trying to refute.
@MetalStorm Also regarding your book request, you cannot seem to find a book that refutes my claim either. So, it seems none of the books have anything to say on this..
Nonetheless, Chet Miller describes an irreversible, isobaric process that has $\Delta H = Q$. Which is essentially what I am claiming is possible, and what you are claiming is not possible.
