Potato mass

[Shrimphead]

Does anybody know the mass of an average potato? I want to make sure that I'm putting the right numbers in on GGDT.
Thanx

Well, you'll be cutting them, so you can basicaly consider them cylinders. They are pretty close to the density of water, so that's 14g/cubic inch. (acctual density is 1.1, so roughly 15.4 g/cubic inch)
In the lakte tests, their slugs where an average of 2" long.

Thus, 28*pi/4*barrel diameter^2
(a 2" barrel would by roughly 120g, for instance)

and what would it be for a 1.5" barrel?

WTF is your problem? Go plug 1.5" into the equation, or if you want 2 digits of accuracy, go look up the actual internal diameter of 1.5".

You can't expect other people to do all your work for you.
