What is the cause of air pressure? Why does the pressure a fluid exerts on the walls of its container decrease when the fluid starts to flow through the container (e.g. a piece of tubing)? Why is it impossible to pull a fluid? What does it mean to "entrain a fluid" into a flow? When the gauge on a cylinder of gas reads zero, is the cylinder actually empty? Explain.

A fluid is a substance that can flow and take the shape of its container. Fluids are characterized…
