Water Viscosity Calculator
When a fluid moves, a shear stress develops in it and its the magnitude depends on the viscosity of the fluid. Shear stress, can be defined as the force required to slide one-unit area layer of a substance (here this substance is a fluid) over another. Therefore, shear stress is a force divided by an area and can be measured in the units of N/m 2 (Pa) or lb/ft 2 . In fluids such as water, oil, or other common liquids the magnitude of the shear stress is directly proportional to the change of velocity between different positions in the fluid and such a change of velocity is also called as shear rate. The constant of proportionality is called the dynamic viscosity of the fluid . The term absolute viscosity is also used for dynamic viscosity. Viscosity, which refers to the resistance of liquids to flow, is influenced by factors such as intermolecular forces, temperature, and molecular shape. Liquids exhibiting strong intermolecular forces generally display higher viscosity compared to...
