What is the applications of drag coefficient in chemical engineers?
Drag coefficients are used in the calculation of particle terminal settling velocity of solids and therefore used where the suspension or settling of solids particle will occur in chemical unit operations. There are hundred of correlations relating the drag coefficient to the particle Reynolds number and some form of measure of the particle shape (i.e sphericity). The particle terminal settling velocity in turn can be used to calculate the hindered settling velocity, so it can be used to help design solid-liquid mixers, clarifiers, thickeners, slurry transport in pipe (i.e design a slurry pump), solid-liquid filters, it can also be used to design pneumatic transport lines to name but a few. It can be used to help design unit operations where solid -fluid (liquid or gas) will need to be mixed, transported or separated.
