capillarityrheometria
Capillarityrheometria is a technique used to study the rheological properties of fluids, particularly those with low viscosity, by observing their flow through capillary tubes. This method relies on the precise measurement of pressure drop across a known length of capillary as a function of flow rate. By analyzing these relationships, researchers can determine key rheological parameters such as viscosity, yield stress, and viscoelasticity.
The fundamental principle behind capillarityrheometria is Poiseuille's Law, which describes laminar flow of a Newtonian fluid
This method is particularly advantageous for small sample volumes and can be adapted for a wide range
