Purpose & Scientific Principle
Viscosity is the internal friction force displayed when the fluid moves. At low Reynolds numbers, it is caused by the thermal motion of molecules and intermolecular attraction. At high Reynolds numbers, it is mainly caused by the movement of molecular groups. The viscosity of air increases as temperature increases. In aircraft design, if the viscous frictional resistance of the air can be reduced, the aircraft can fly faster.
How to Operate
This exhibition item uses a mechanical interactive device to push the push rod and observe the phenomenon of its driven rotation with the motor rotating mechanism without contact. Through experiencing this exhibition item, you can have a better understanding of the viscosity of fluids.
1. Press the start button, and the disc on the motor shaft starts to rotate. At this time, the disc on the other side of the moving disc remains stationary because it is far away.
2. Push the push rod to adjust the distance between the two discs. When it reaches a certain position (there is no contact between the flying discs), the disc on the other side will also rotate with the rotating disc.
