Pressure due to uneven water distribution in connecting pipe

In summary, the conversation is about a fluid system with points A, B, C, and D. The question is asking for the formula to calculate the pressure at point D, which is related to the pressure at point C by 12h. The answer given includes 15h, which is the pressure at D related to atmospheric pressure. The conversation also includes some clarifications and suggestions for finding the pressure at each point in the system.

The Attempt at a Solution


Im confused by this question, just looking at the diagram without any maths you can see what would happen. C and D would want to reach equilibrium and be at the same level so the pressure down on D would be the difference in heights of the fluid. ie. 12 h times p g. but the equation says 15 not sure how they arrived at that? could anyone here help please? i am trying to get the formula given

The 15h in the answer relates the pressure at D to atmospheric pressure. You are right that the pressure at D is related to the pressure at C by 12h.

Many thanks for the reply! ok so the pressure at D, is the atmospheric pressure minus (because it acts in the opposite direction) the pressure due to unequilibrium? I still can't see where the 15 comes from, please could you expand a little? thanks again

See if you can work your way through the system point by point. Find P at A, then B, then C, then D. (You can probably skip A.)

ok will try that, thanks again!
 

1. What is pressure due to uneven water distribution in connecting pipe?

Pressure due to uneven water distribution in connecting pipe refers to the unequal distribution of water pressure within a pipe system. This can occur when there is a blockage or constriction in the pipe, causing the water to flow more slowly in certain areas and creating areas of high and low pressure.

2. How does pressure due to uneven water distribution affect the flow of water?

Uneven water distribution can cause disruptions in the flow of water, resulting in areas of high pressure where the water is forced through and areas of low pressure where the water flows more slowly. This can lead to inefficient water flow and potential damage to the pipe system.

3. What are the potential consequences of pressure due to uneven water distribution in connecting pipe?

The consequences of uneven water distribution can range from decreased water flow and pressure to damage to the pipe system. In extreme cases, it can also lead to burst pipes and water leaks, which can cause water damage to surrounding areas.

4. How can pressure due to uneven water distribution be detected?

Pressure due to uneven water distribution can be detected by monitoring water flow and pressure in different areas of the pipe system. This can be done using pressure gauges or by observing changes in water flow from faucets or other outlets.

5. How can pressure due to uneven water distribution be fixed?

The best way to fix pressure due to uneven water distribution is to identify and address the source of the problem. This may involve removing blockages or obstructions in the pipe system, repairing or replacing damaged pipes, or adjusting the water pressure regulator to ensure more even distribution. Consulting a professional plumber may also be necessary for more complex issues.
