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.

this topic is under the Fluid Mechanics branch. the drag force can be applied in many things with regard for chemical engineering. for example, in a stream of air Oxygen can be absorbed by another media,now knowing the drag force for air that will indicate along with diffusion rate of Oxygen into the media how much Oxygen has been transferred.
also. if you want to calculate the temperature profile for some application that use air as a cooling media, drag force can be used.
in separation drag force will tell you how much component A has moved a long with component B depending on the drag force of B
