Solid The speed of sound in a solid material with a large cross-section is given by c B G = + 4 3 ρ (9) where G is the shear modulus, ρ is the mass per unit volume. Equation (9) is taken from equation (6.41) in Reference 1. The c term is referred to as the bulk or plate speed of longitudinal waves. The shear modulus can be expressed as 2(1

    Nov 02, 2014 Helical / Spiral Chute Development. During the design phase of the project, we discovered that using a spiral / helical chute for the gentle handling of bulk materials inside a silo is totally different from discrete package handling and had its own host of design issues to resolve. The design of the helical chute needs to accommodate several

When a feeder is turned on, there should be a close correlation between its speed of operation and the rate of discharge of the bulk solid. Feeders differ from conveyors in
