what is meant by constraint forces? do they refer to the forces that are considered non conservative? how can I distinguish them from other forces?

Constraint forces are defined as forces that restrict the motion of a system, ensuring that certain conditions or constraints are met. They are typically non-conservative, meaning they do not store energy and do not perform work on the system. To distinguish constraint forces from other forces, one should consider their role in maintaining specific conditions, such as tension in a rope or the normal force from a surface. Understanding the nature of these forces is crucial for analyzing mechanical systems and their behavior under various conditions. Proper identification of constraint forces aids in the accurate application of Newton's laws and energy principles.
As you can see from the picture, i have an uneven U-shaped tube, sealed at the short end. I fill the tube with water and i seal it. So the short side is filled with water and the long side ends up containg water and trapped air.
Now the tube is sealed on both sides and i turn it in such a way that the traped air moves at the short side.
Are my claims about pressure in senarios A & B correct?
What is the pressure for all points in senario C?
