When one envisions transporting bulk materials efficiently through pipelines, understanding the specific calculations for these systems becomes paramount. This article delves deep into the calculations of the dilute phase pneumatic conveying system, offering a step-by-step guide on the critical formula and its variables.
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 6-12 PSIG, have a terminal velocity of between 4,500 – 6,000 fpm ...

An empirical model to calculate the pipe line pressure loss for a pneumatic conveying system is described. The model was originally proposed for lean phase conveying and is modified to use solids friction proposed by Weber (1982). The calculated pressure loss for a given pipe diameter, pipe length, air mass flow rate and material mass flow rate is compared to recent experimental …
The proposed system replaces existing conveying system to pneumatic conveying system. Pneumatic conveying system is more advanced and effective mode of conveying. Since pneumatic systems are closed the chance of spillage is minimized. The benefit estimation and design layout is drawn along with n calculation of the overall system.
Contrary to the method proposed by Rhodes, this method is mainly empirical and relies 1st on the calculation of the pressure drop of the conveying flowing alone (air ONLY). From this pressure drop, a correlation is applied to estimate the pressure drop when materials is transported. This … See more

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.
