Conversion between dynamic viscosity and kinematic viscosity
Dynamic viscosity η Kinematic viscosity υSample density ρ
Kinematic viscosity υ = dynamic viscosity η / sample density ρ
Dynamic viscosity η=kinematic viscosity υ * sample density ρ
Classification of fluid
Fluids can be divided into Newtonian fluids and non-Newtonian fluids. A Newtonian fluid is a fluid whose viscosity value does not change with the shear rate, but remains constant. A fluid whose viscosity varies with rotational speed/shear rate is called a non-Newtonian fluid. Non-Newtonian fluids are divided into two categories, one category: fluids whose viscosity only changes with the change of shear rate. The second largest category: Fluids whose viscosity changes with the change of shear rate and the extension of measurement time.
Viscosity of Common Fluids
Viscosity refers to the fluidity (or immobility) of a substance, and its unit of measurement is centipoise. Water has a viscosity of 1 centipoise and flows easily.
1 centipoise = water; 3.2 centipoise = milk; 16.5 centipoise = cream; 34.6 centipoise = vegetable oil; 176 centipoise = tomato paste;
880 centipoise = glycerin; 1760 centipoise = molasses (Molasses); 3000 centipoise = glue; 8640 centipoise = syrup B; Compare. The unit is (m^2)/s. Indicated by a lowercase letter v.
Note: The unit that has been used is St (S)
The rate relationship between St (S) and (m^2)/s is: 1(m^2)/s=10^4St=10^6cSt. (where "cSt" is read as "centistokes")
