Purpose & Scientific Principle
The exhibits are intended to display knowledge about siphon drainage, the reaction force of water, etc. Watching the water lifting process of the water truck, the siphon scene and the water flow impingement drum device can allow children to deeply feel the application of water in daily production and cultivate their thinking ability.
How to Operate
The exhibition items mainly consist of waterwheel devices, siphon devices, recoil drums, handwheels, etc.
There are several "bucket"-shaped containers evenly distributed on the circumference of the Rainbow Waterwheel, and the containers are installed at a certain angle to the circumference of the wheel. The audience turns the handwheel to drive the container to move in a circular motion from low to high. The angle of the container is designed so that when it is at a low position, it enters the pool, and water can be filled into the container. When it is turned to a high position, the water can be poured into the diversion channel. Through the siphon mechanism, the water is sucked into the recoil drum. Under the action of the recoil force, the drum rotates in the opposite direction of the water flow.
The siphon phenomenon uses the principle of pressure difference. In a closed container, the height of the liquid is the same and the pressure is equal. The siphon is filled with water and has no air. The water level at the inlet end is high, and the water outlet is closed with the palm of your hand or other objects. At this time, the pressure inside the pipe is equal everywhere. After everything is set up, open the water outlet. Although the atmospheric pressure on both sides is equal, the water level at the inlet end is high and the pressure is strong, pushing the incoming water to continuously flow out of the outlet.
The action force is the force generated by the interaction between two objects through different forms, such as attraction, relative motion, deformation, etc.
Reaction force is opposite to "action force". In mechanics, forces always appear in pairs. One force (called action force) corresponds to a force of equal magnitude and opposite direction called reaction force.
