LMEC-11 Measuring Liquid Viscosity Falling Sphere Method

Measuring Liquid Viscosity Falling Sphere Method Liquid viscosity coefficient, also known as liquid viscosity, is one of the important properties of liquid, which has important applications in engineering, production technology and medicine. The falling ball method is very suitable for the experimental teaching of freshmen and sophomores because of its obvious physical phenomenon, clear concept and many experimental operations and training contents. However, due to the influence of manual stopwatch, parallax and the ball falling off the center, the accuracy of falling speed measurement is not high in the past. This instrument not only retains the operation and experimental content of the original experimental device, but also adds the principle and use method of laser photoelectric timer, which expands the scope of knowledge, improves the accuracy of measurement, and embodies the modernization of experimental teaching. Features 1. Adopt laser photoelectric gate timing, more accurate me
