    Pressure Volume
Click For Summary
In a scenario with two closed containers of different air volumes submerged in water, the pressure sensor in the smaller volume container will read a higher pressure. This occurs because the pressure in the gas equals the pressure at the liquid surface inside the tube. Consequently, the right sensor can exert more force, pushing water further down than the left sensor. The difference in air volume affects the pressure readings despite both sensors being influenced by the same water level. Thus, the right container's sensor will indicate a higher pressure due to its ability to push water more effectively.

If you had pressure sensors (red) inside closed containers (black). The one on the left having more air volume than the one on the right. They are inside a bucket (green) that is filled with water. The water will rise higher in the left container. Will the pressure sensor readings be identical or will the right one read higher?

The pressure in the gas will be the same as that at the liquid surface inside the tube.
 
The right pressure sensor will read a higher pressure.
It is able to push water further downwards than the sensor on the left.
 
I built a device designed to brake angular velocity which seems to work based on below, i used a flexible shaft that could bow up and down so i could visually see what was happening for the prototypes. If you spin two wheels in opposite directions each with a magnitude of angular momentum L on a rigid shaft (equal magnitude opposite directions), then rotate the shaft at 90 degrees to the momentum vectors at constant angular velocity omega, then the resulting torques oppose each other...
