I am new to fluid mechanics and am trying to understand the fluid mechanics of a simple valve.
Let's assume we have a simple tube, which is supplied with a constant stream of liquid using a pump. At the end of the tube is a valve, which closes periodically. What kind of changes, would I except in the tube due to the closing of the valve?
In my naive understanding, I would assume, that the velocity should approach zero (since there is no way, where the fluid could go), however the pressure should stay constant - there is no fluid flow, but the pump provides still constant pressure.
Is this understanding correct? Do you maybe have some papers / literature / videos, where this is explained in more (maybe mathematical) detail?
Thank you very much!!
