SUMMARY

The discussion centers on the behavior of water in a vertical tube under varying pressure conditions. A 1-inch diameter tube, 7 feet high, contains 5 feet of water, with a vacuum pressure of -1 psi above the water. The downward pressure from the water column is 3 psi, leading to the conclusion that the water level will remain unchanged due to the insufficient vacuum pressure to overcome the downward force exerted by the water column.

PREREQUISITES
  • Understanding of fluid mechanics principles
  • Knowledge of pressure measurements, including psi and vacuum pressure
  • Familiarity with atmospheric pressure effects on liquids
  • Basic concepts of hydrostatic pressure
NEXT STEPS
  • Research hydrostatic pressure calculations in fluid mechanics
  • Learn about the effects of vacuum pressure on liquid columns
  • Study the principles of atmospheric pressure and its impact on fluids
  • Explore practical applications of suction forces in fluid systems
USEFUL FOR

Students studying fluid mechanics, engineers working with hydraulic systems, and anyone interested in the principles of pressure and vacuum in liquids.

Homework Statement



I'm stuck on a problem. If you have a 1'' diameter tube running vertically about 7 feet in the air and 5 feet of the tube was full of water. And at the top of the tube was closed off. And the 2 feet above the water had a vacuum pressure of negative 1 psi.(I don't know vacuum measurements so I put it as a negative psi) Would the water rise upward to the vacuum area. or because the water would have a downward pressure of 3 psi would the water level remain the same.

Homework Equations





The Attempt at a Solution

 
Physics news on Phys.org
I'm just wondering because I know if you want to rise water around 34 feet in the air you would have to have a suction force of around 14 psi. Then the water pressure equals the atmospheric pressure. But if you have let's say a bowl of water with a 7 foot pipe running vertically and if the water in the pipe is at 5 feet. It would have a downward force of 3 psi. Now if you had a low vacuum in the pipe, less than 3 psi worth. Would the water rise because of the atmosperic pressure pushing the water upward. Or would the vacuum force be too weak to affect the water.
 
Does anyone know the answer to my question.
