Dynamic viscosity wikipedia

WebViscosity is a physical property of fluids. It shows resistance to flow. [1] In a simple example, water has a low viscosity, as it is "thin". Syrup and tar, on the other hand, have a high viscosity, as they are "thick". A way to test for viscosity is the speed at which the substance runs down a slope. Syrup would reach the bottom very slowly ... WebFor one particular complexing agent, the viscosity is very high, but when I measured the modulus (elastic and loss modulus) with frequency, it was very low. I do not know how to corrrelate both.
