This article reacquaints the reader with the basic concepts and terminology for viscosity and addresses techniques to quantify it. The bottom line is to come up with ways to measure viscosity so that you can quantify whether a material will flow the way it needs to. For handlers of all materials that flow, either while being processed or in an end-use, it is important to think about the materials’ flow characteristics. To be brief, viscosity is resistance to flow.
Most engineers know what viscosity is, but may have trouble explaining it.
