Head loss equaling head pressure?

Click For Summary

Discussion Overview

The discussion revolves around the relationship between head loss and head pressure in a fluid flowing through a pipe. Participants explore the implications of head losses equaling head pressure, focusing on fluid dynamics and flow rates.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant questions what occurs when head losses equal head pressure in a fluid system.
  • Another participant suggests that a constant flow rate may result from this condition, noting that pressure loss typically occurs only during flow.
  • A participant references the relationship between pressure drop and flow rate in pipelines, implying a connection to the discussion but without elaborating on its relevance.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the implications of head losses equaling head pressure, and multiple viewpoints are presented without resolution.

Contextual Notes

The discussion does not clarify specific assumptions about fluid properties, pipe characteristics, or flow conditions that may influence the relationship between head loss and head pressure.

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.
