Re: Silage

[Subject Prev][Subject Next][Thread Prev][Thread Next]
The Midwest Plan Service publication Structures and Environment Handbook, MWPS-1 10th edition, 1980 says that the National Silo Association recommends an Equivalent Fluid Density of 20 psf for designing silos containing corn silage at 68%-72% moisture content. The NSA recommends that a maximum density , 65 pcf, and a minimum angle of internam friction, 32 degrees, be used in Rankine's equation to obtain an Equivalent Fluid Density of 20 pcf/ft.

I have been asked to design a divider wall in a horizontal silo. Any
ideas as to the lateral pressure from corn or hay silage? The height of
the wall is 18'. The length of the wall is 100 feet.
