Item Type:

Glass Tube Connector

Material:

Glass

Size:

Approx. 18 x 14.5cm / 7.1 x 5.7in

Application:

1. Help initially known that the fluid is fluid :

2. A preliminary understanding of the relationship between fluid pressure and rate :

How to Use:

1. Put the instrument in the picture on the bracket, plug the valve with a plug, and let the water into the transparent tube with different pipe diameters, such as the glass tube shown in the picture. The section at A is larger than that at B. Vertical glass tubes a and b are installed at and B respectively. :

2. Slowly loosen the stopper to control the water speed, and continue to add water. When the water flows in the glass tube, you can see that the liquid level in tube a is higher than that in tube b, which shows that the pressure at A is higher than that at B. At B, where the cross-section is smaller, the water is more concentrated, and the water velocity is obviously greater than at A. This means that the fluid has a lower pressure where the velocity is high, and a higher pressure where the velocity is small. :
