Flow velocity measurement principle is an important method to study fluid motion. By measuring the velocity and direction of fluid motion, the motion state of the fluid at different positions is revealed. Flow velocity measurement principle is based on Newton's second law, and the flow velocity is determined by the shear stress acting on the fluid. Flow velocity sensors or experimental particle tracking methods are usually used to measure the velocity and velocity field of the fluid. In practical applications, factors such as Reynolds number and viscosity need to be considered to ensure the accuracy of the measurement results. Through the principle of flow velocity measurement, we can understand the flow of fluid in pipelines, airflow distribution in wind tunnel tests, and provide important references for engineering design and scientific research.。
