With : u pickup = pick-up air velocity in conveying pipe of diameter D at the point of entry of the solids (m/s) Q airin = air volumetric flow rate at the inlet of the solids (m3/s) D in = pipe diameter at the inlet of solids (m). Reversely, defining the minimum air conveying velocity and thus the pick-up speed can be used to calculate the required air flowrate and then specify a new system.

Introduction to Pneumatic Conveying of Solids

What is pneumatic conveying? Pneumatic conveying is the movement of solids through pipe using gas (usually air) as the motive force. It differs from hydraulic or slurry conveying in that the gas expands continuously along the pipe length. The flow regime in the pipe depends greatly on the ratio of solids to gas and the particle characteristics.

Answers to Eight Common Questions about Pneumatic Conveying

A pneumatic conveying system typically requires far more horsepower to operate than an equivalently sized mechanical conveying system. The reason is that changing the air pressure to achieve pneumatic conveying consumes a large amount of power and is inherently less efficient than a mechanical conveying system's mechanical transfer.
