Fluid viscosity problem
Thread Content
Generally speaking, at what viscosity level does a fluid’s viscosity begin to affect its flow? Or it affects the operation of the equipment: lol
That’s too general. What device?
The property that causes the aforementioned internal friction when a fluid flows is called viscosity, while the physical quantity that indicates the degree of viscosity (the magnitude of the frictional resistance that arises when molecules within a liquid move relative to each other) is known as dynamic viscosity. The higher the viscosity of a fluid, the worse its flowability. For example, oil has a higher viscosity than water, and its fluidity is worse than that of water ； The viscosity of the fluid is very high, making it difficult for it to flow; screw pump types can be used as seals. This property of viscosity is of great significance for studying fluid flow as well as processes such as heat and mass transfer in fluids.
