Can Different Radii of Pipes Affect the Height of Liquid in a Tank?

Click For Summary

Discussion Overview

The discussion revolves around the question of whether different radii of pipes can affect the height of liquid in a tank. Participants explore the relationship between pipe radius and liquid height, considering both theoretical and practical implications.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant suggests that the height of the liquid is a function that varies inversely with the radius of the pipe, noting that significant height differences are typically only observable with capillary tubes of smaller radii.
  • Another participant argues that pressure determines the height of the liquid in the pipes, stating that if the pipes are connected to a static system, they will maintain the same height as the liquid in the tank regardless of radius.
  • There is some confusion regarding terminology, with multiple participants correcting the use of "radios" to "radius" or "radii."

Areas of Agreement / Disagreement

Participants express differing views on the influence of pipe radius on liquid height, with no consensus reached on the matter. Some argue for the inverse relationship, while others emphasize the role of pressure in a static system.

Contextual Notes

Participants note that significant height differences may require specific conditions, such as using capillary tubes, and that the discussion is limited by assumptions about the system's static nature.

if i put two pipes in atank of some liquid and fill it up, will the height of the liquid be different in the pipes if the radios will be different?
if not how can i create asituation so the height of the liquid will be different?

I think the OP means "radius" or "radii".

Yes, the height of rise is a function (it varies inversely) of the radius of the pipe. However, note that there will be no noticeable rise if the radius is more than a centimeter or so, for a typical liquid. To see a significant height difference you should use capillary tubes (not pipes) with radii that are in the mm range.
 
thanks you were right it was radius:)

[Assuming I understand your question...] You can't. Pressure is what determines the height of the water in the two pipes. As long as they are connected to a static system, they will have the same pressure at the same height - ie, exactly the same as the height of the water in the tank next to them.
