Sizing Example:
Company wants to ship 2,200 Ibs. of alfalfa seed per bag.
I What size container do you need?
=
2,200 Ibs. / 48 Ibs. per cubic foot
(bulk
density of alfalfa seed per cu.ft.)
46
(Therefore a 46 cu.ft. Super Sack container is needed)
cU.ft.
2 Next, you need to determine the Filled Height and Empty Height.
=
46 cU.ft. / .92 (factor - see chart below) = 50" Filled Height (+4"
Empty Height)
3 Your size would be:
35" x 35" x 54" (50" Filled Height) with a 45" dia. and 2,200 Ibs. product capacity.
