Description:The communicating device is two or more containers that communicate with each other below the liquid level. The connector with the same liquid and equal pressure on the liquid surface has the same liquid level. Specifications:Material: Glass, plastic Features:- The communicating device contains the same liquid, but the pressure on the liquid surface is not equal, the pressure difference of the liquid surface is equal to the pressure difference generated by the liquid level difference between the two containers of the communicating device;- The pressure on the liquid level of the connected device is equal, but there are different liquids that are not mixed with each other. The height of the two liquid surfaces is inversely proportional to the liquid density from the interface;- The principle of the linker has a wide range of applications in engineering. Such as various liquid level gauges (water level gauges, oil level gauges, etc.), mercury vacuum gauges, liquid column air pressure gauges, differential pressure gauges, gas leak detection devices, etc., are all made using the principle of the connector;- Has a good experimental display effect. Package Included:1 Pcs x Glass Connector
