China Wholesale Surface Tension Quotes – LMEC-11 Measuring Liquid Viscosity – Falling Sphere Method – Labor
China Wholesale Surface Tension Quotes – LMEC-11 Measuring Liquid Viscosity – Falling Sphere Method – Labor Detail:
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.
Functions
1. Using photoelectric sensor and electronic timer to avoid the parallax and timing errors caused by a stopwatch
2. Improved mechanical design to ensure precise falling trace of the sphere
3. Using laser ranging to accurately measure both the fall time and fall distance to avoid the parallax error
Using this apparatus, the following experiments can be conducted:
1. Measure the viscosity coefficient of a liquid using falling sphere method
2. Use a photoelectric sensor for timing experiment
3. Use a stopwatch to time a falling sphere, and compare results with the photoelectric timing method
