Air mass balance for mass flow rate calculation in pneumatic conveying
To find mass of solids Eq. (3) is multiplied by ρs / ρa, (4) ρ s V p = V s ρ s + C ρ s ρ a where (5) C = ρ a V a C can be calculated and it represents mass of air (kg) contained in the pipe section. Therefore, the mass of solids contained in the pipe section under study at a time t is: (6) m s = ρ s V p − C ρ s ρ a.

A simulation system for pneumatic conveying systems
Tomas Marsh. Pneumatic conveying is the transportation of bulk solids in enclosed pipelines via a carrier gas, typically air. The local flow pattern in a pipeline is a function of the conditions, and slug flow can form under certain conditions. Slug flow is a naturally occurring, wave-like flow where the bulk material travels along the pipeline ...
