Angle of Internal Friction

[minorchord2000]

I am structural engineer and have been tasked to design a rectangular bin hopper the contents of which is abrasive slurry with a specific gravity of 1.16. Can anyone give me the approximate angle of internal friction?

If there is no cementing together of the material, I'd measure the angle of slope above horizontal for a loose pile placed by placing by gravity from the top, but at least 30 degrees.

...and less if you use marbles.

liquids don't have friction angles. They have viscosity.

If it's a solid (i.e., or plastic), we can help you.

I would not assume that a "slurry" has an internal friction angle or shear strength. I may be conservative but I would assume a liquid head.
