Solid In Air Diffusion Apparatus With Data Logging Facility

Confirming a packed bed of spherical balls of a solid in a vertical tube, and observing its rate of diffusion into stream of air passed across the top of the tube can conveniently study the diffusion of solid into air. The equipment is fitted with a vertical glass column with a mesh near the base of column to hold the spherical balls. Spherical balls of known weight and diameter are filled in t
