Head loss equaling head pressure?

AI Thread Summary
When head losses in a pipe equal the head pressure, the flow rate remains constant. Pressure loss in a pipe typically occurs when there is fluid movement, with losses being proportional to the square of the fluid velocity. A pressure drop of 10 meters of water head indicates a specific flow velocity for that pipe. Understanding this relationship is crucial for effective fluid dynamics management. The discussion highlights the importance of recognizing how head pressure and head loss interact in pipeline systems.

If you had a fluid in a pipe, with say, 10m of head pressure, what would happen when the head losses of the pipe equaled the head pressure?

Any ideas? Maybe a moderator could move this to a more appropriate forum if necessary?
 
I believe you get a constant flow rate.

You normally only get a pressure loss in a pipe when there is some flow (As I recall pressure loss is roughly proportional to fluid velocity squared). So a pressure drop of 10m head of water would occur at some velocity of water specific to that pipe.
 

Thread 'Is calling fictitious forces "not real" just about terminology?'

Hi there, im studying nanoscience at the university in Basel. Today I looked at the topic of intertial and non-inertial reference frames and the existence of fictitious forces. I understand that you call forces real in physics if they appear in interplay. Meaning that a force is real when there is the "actio" partner to the "reactio" partner. If this condition is not satisfied the force is not real. I also understand that if you specifically look at non-inertial reference frames you can...

Thread 'Derivation of Hamilton's Principle: Questions'

I have recently been really interested in the derivation of Hamiltons Principle. On my research I found that with the term ##m \cdot \frac{d}{dt} (\frac{dr}{dt} \cdot \delta r) = 0## (1) one may derivate ##\delta \int (T - V) dt = 0## (2). The derivation itself I understood quiet good, but what I don't understand is where the equation (1) came from, because in my research it was just given and not derived from anywhere. Does anybody know where (1) comes from or why from it the...
