Math ? - corn - volume on a cylinder

[TXBRASS]

From another post: Corn is around 45 lbs/cu. ft which equates to 38.4 cu. in/lb

whole cotton seed is around 22 lb/cu. ft which equates to 78.5 cu. in/lb

Pipe is sized by the ID. Tubing is sized by OD.

Pipe is sized by the OD on anything above 12". We were just giving the op a hard time

Pipe is sized by the OD on anything above 12".

Bet me to it.

Pipe sizes are one of my pet peeves. Its like fingernails on a chalkboard when I hear people say they have some 2 3/8 pipe.
