FlowBenchCalc

What is it about?

FlowBenchCalc is a quick, easy tool for powder flow checks in the lab or on the plant floor. It lets you compute the Hausner Ratio, Carr’s Compressibility Index, Flow Function Coefficient, and a Flowability Index from flow time with simple steps. A guided Shear Cell Test screen walks you through the inputs and shows clear results. It also estimates wall friction angle and sifting time so you can spot flow risks early. Need design help? It predicts arching diameter, the hopper half-angle you should use, and the critical outlet size to keep flow smooth. Type your numbers once and get instant answers, units, and short notes in plain words. No heavy math or long menus—just clean screens that help you decide fast. Great for quick checks, trials, and simple go/no-go calls.
