I googled the diameter of a gnat's anus, but couldn't find an authoritative
source. I did find some electron microscope photos though, and I'd estimate
it at around 0.0002 inches. That may be sufficient.
Thanks for the source, Lloyd.

Ben,
I found a better link for premixed LOX/CH4
Advances in Cryogenic Engineering: Volume 17 pg 188-191
Google Books Link
<https://books.google.co.nz/books?id=AuPgBwAAQBAJ&pg=PA188&lpg=PA188&dq=rocket+monopropellant+critical+diameter&source=bl&ots=SbfrBDrE_E&sig=uLH4JaNLJLz-tOYGw9JOVkMVcvQ&hl=en&sa=X&ved=0ahUKEwi8n-Gr_cLJAhUjOKYKHVuaB3QQ6AEIKTAC#v=onepage&q=rocket%20monopropellant%20critical%20diameter&f=false>
TL:DR The critical diameter for LOX/LCH4 is less than 0.006" if it exists
at all.

Good to know, I'd forgotten that exchange. I return to thinking that
lox/ch4 monopropellant is completely crazy, not just mostly. Thanks!

O'Hara et al. (1972) seem to believe it's basically zero:

By the way, does anyone know how to get a hold of the NASA
lox-methane-monoprop bibliography mentioned in the message linked to above?

Again only tangentially related, but anyone happen to have seen the
critical diameter of mixed LOX/Methane? I still think it's insane to
have it in a tank as a monopropellant, but mixing it and injecting it
into a thrust chamber through porous sintered metal or laser drilled
micro holes could give interesting results if it doesn't explode.
