Key dilute-phase equations II — Pressure and pressure drop
Building on the information presented in his first series of columns, Paul E. Solt -- a private consultant with more than 35 years experience installing and troubleshooting pneumatic conveying systems -- presents a second series of columns discussing pneumatic conveying basics and how to apply them when designing a pneumatic conveying system.
In this fourth column, we'll continue to look at equations applying to dilute-phase [stream flow] conveying. As the second column [July 1991] discussed, dilute-phase conveying occurs when the air velocity in the conveying line is high enough to keep the material in suspension.
