I would imagine it depends on internal pressure, the tightness of the sphincter, and whether there are any "obstructions" in the lower bowel  [xx(]

The volume of the fart divided by the product of the area of the hole and the duration.

Perhaps there is a calculation there somewhere involving the pitch of the sound made also?!!!

I agree....I expect the same variables are applicable to stipulating the speed of a sneeze too !

Presumably it is the area of the hole whilst during the actual act of guffing yes ?

Yes, though I have to say I never thought that I'd be putting my very expensive university education to problems of this importance.
