The discussion centers on the physics of fluid dynamics as demonstrated by a water bottle with a valve and a small hole. When the valve at the top of the bottle is open, water flows out of the hole due to atmospheric pressure. However, when the valve is closed, the flow stops because the air pressure inside the bottle cannot equalize, creating a vacuum effect that halts the water's exit. This illustrates fundamental principles of pressure and fluid mechanics.
PREREQUISITESStudents of physics, engineers, and anyone interested in understanding fluid dynamics and pressure systems will benefit from this discussion.
Can you please explain furtherjbriggs444 said:As I understand it, you have a bottle with an opening at the top and a valve on the opening.
You have added a small hole at the bottom (small enough so that air does not bubble in through it). You notice that when the top valve is open that the water flows freely out the bottom. But if you close the valve at the top, water no longer flows out.
If you leave the valve open at the top, does anything flow into the bottle through the opening?
If you close the valve, what happens to the air pressure in the bottle above the water if some water, hypothetically, continues to flow out the hole?
Can you answer either question?Einstein60 said:Can you please explain further
