JBT07C Dynamic bubble pressure gauge

Introduction :

In a sample container with a constant temperature, a capillary tube is immersed into a liquid at a given depth, which is connected with a gas interface and a sensitive pressure sensor.

When the bubble pressure gauge JBT07 increases the flow rate of gas, the bubble formation frequency is accelerated, and the survival time of each bubble is reduced accordingly.At the beginning of the experiment, the formation of a bubble takes two seconds, and the end of the experiment can form ten bubbles per second.When the bubble radius is equal to the capillary radius, the bubble pressure reaches the maximum value.When the bubble radius exceeds the capillary radius, the bubble pressure decreases significantly. The maximum pressure and the dynamic surface tension is proportional to the dynamic surface tension. Hydrostatic pressure P is proportional to the immersion depth of the capillary.
