In line with this thread and topshot's suggestions I would (and by the way I am, at this moment) attempting to determine the internal pressure of an elk size animal.
I have the density down pat!
Now I need an internal pressure.
The only elk sized animals that are handy and would tolerate the treatment would be one of the neighbor's horses.
I figure a differential pressure sensor with one pressure probe carefully inserted into it arse with the other dangling in the atmosphere would do. With the output connected to an A/D converter and that USB'd into the laptop. I could wait until it farted. Me being down wind would feel comfortable with this position. However anyone who says a horse fart smells bad may lie about other things too.
A plot of the D/P sensor's output would show the pressure curve revealing the fart max, mean and starting pressures. Average internal pressure would then be extrapolated from the data.
Or I could rig up a fish-d-lier scale to work backwards and press on its paunch until I figgered that it felt about right and use that weight/square area for the number.
Or I could.......nah, better not reveal that one.
You guys are reading all of this, huh? LMAO!!!!!!
I'm off to see what it takes to get a shoulder blade out of a butcher.
