In open end pipe line suspension flow, or dilute phase pneumatic conveying, proper particle velocity is critical to continuing productivity and product quality. Until recently, measurement of actual particle velocity within the pipe has not been practical outside the laboratory.

SIZING A PNEUMATIC CONVEYING SYSTEM
As a general rule in pneumatic conveying, when sizing a system we look primarily at pressures, velocities and line loadings to determine best what the line size should be. For example a well sized dilute phase pressure system going 200 feet would probably run somewhere between 612 PSIG, have a terminal velocity of between 4,500 – 6,000 fpm ...
