Kinematic viscosity, is the fluid viscosity and is the isthethermaldiffusivitywith fluiddensity, = / is the heat being the fluid thermal conductivity and capacity at constant pressure. Viscosity measurement using nuclear magnetic resonance (NMR) is a novel viscosity test method developed in recent years, which has the advantages of noncontact and wide application range and so on and has broad application prospects in in situ viscosity measurement of fluid in rock porous media. The accurate prediction and measurement of the behavior of a fluid in motion is essential in the design of efficient industrial plants and apparatus.
The viscosity of engine oil is mentioned often in the auto industry but what is its meaning? Learn how oil types & specs can impact your car and driving experience. This works well for fluid with no viscosity, but for viscous liquids it can lead to particles creeping off the surface even with very high viscosity. Fluid Viscosity, sometimes referred to as dynamic viscosity or absolute viscosity, is the fluid's resistance to flow, which is caused by a shearing stress within a flowing fluid and between Dynamic Viscosity / Absolute Viscosity.
