What are Viscosity Flow Curves?
A flow curve – also known as a rheogram – is a graphical representation of how a flowing material (fluid) behaves when it is subjected to increasing or decreasing shear rates. The corresponding shear stress and viscosity are calculated from the instrument’s parameters. You can tell what type of fluid (Newtonian/Non-Newtonian, thixotropic, dilatant, etc.) the sample is by the shape of the flow curve.Read More
