Description

technical field [0001] The invention relates to the technical field of fluid physical property measurement, in particular to a viscosity testing device and a testing method thereof. Background technique [0002] Viscosity is an important parameter to characterize the properties of fluids and directly reflects the characteristics of different fluids. Viscosity measurement is widely used in various social production fields. The flow of fluid is a continuous deformation process under the action of gravity or other external forces. For example, when fluid flows in a pipe, the flow velocity at the central axis of the pipe is the fastest, and the closer to the pipe wall, the slower the flow velocity. This shows that when the fluid flows The speed of each part of the interior is different. There is a speed difference between the flow layers, and the motion of the fluid is transmitted layer by layer. The transmission of this speed difference is due to the viscosity of the fluid. Thi...
