Splet21. sep. 2024 · 2. Sutherland's Law seems to be a fairly well-accepted relationship between dynamic viscosity and temperature and was originally created to work for ideal gases, though it is often extended to be used for atmospheric air. μ = μ r e f T T r e f 3 / 2 ( T r e f + S T + S) T r e f = reference temperature. μ r e f = viscosity at T r e f. SpletDynamic viscosity of fluid = ( (Constant a)* (Temperature^ (1/2)))/ (1+Constant B/Temperature) μd = ( (a)* (T^ (1/2)))/ (1+B/T) This formula uses 4 Variables Variables Used Dynamic viscosity of fluid - (Measured in Pascal Second) - Dynamic viscosity of fluid is the measure of its resistance to flow when an external force is applied.

Momentum transport in gases is mediated by discrete molecular collisions, and in liquids by attractive forces that bind molecules close together. Because of this, the dynamic viscosities of liquids are typically much larger than those of gases. In addition, viscosity tends to increase with temperature in gases and decrease with temperature in liquids.
