Gas-Flow Calculations for Sonic Choking: Revisited

Gas compressibility can lead to choked flow in piping systems. Presented here is an overview of choked-flow geometries in pipes, and examples of how choked flow arises in different pipe layouts The more things change, the more they stay the…

Focus On: Laboratory Equipment

Monitoring capabilities for shared laboratory spaces This product, launched as part of this company’s Dashboard solution (photo), is designed to add alerting capabilities to centrally located devices within a shared laboratory space, such as a cleanroom. The product introduces visual…

AI’s potential in the CPI

One of the aspects of my job that I really enjoy is keeping in touch with new and advanced technologies emerging from the chemical process industries (CPI) — an interest that traces back to my roots as an R&D engineer.…

Facts At Your Fingertips: Blending and Segregation Mechanisms for Solids

In solids-handling, blending (combining two or more materials to achieve a combined product) and segregation (the separation of particles into distinct zones according to particle size, shape, density or other physical attributes) are competing processes. This one-page reference outlines common…
