Pressure Variation in a Tilted Fluid Column

Click For Summary
SUMMARY

The discussion centers on calculating the gauge pressure at the top of a tilted fluid column in a tube filled with a sterile solution of density 1037 kg/m³. The tube, measuring 0.3 m in length and tilted at an angle of 40°, has a gauge pressure of 3000 Pa at its base. Participants emphasize the need to account for the change in vertical height due to the tilt, suggesting the use of Bernoulli's equation and the relationship p = ρgh to determine the pressure variation accurately.

PREREQUISITES
  • Understanding of fluid mechanics principles, particularly hydrostatic pressure.
  • Familiarity with Bernoulli's equation and its applications.
  • Knowledge of trigonometry to calculate vertical height in tilted columns.
  • Basic proficiency in pressure units and conversions (Pa, gauge pressure).
NEXT STEPS
  • Study the application of Bernoulli's equation in fluid dynamics.
  • Learn how to calculate pressure differences in tilted fluid columns using trigonometric functions.
  • Explore hydrostatic pressure calculations for fluids of varying densities.
  • Investigate the effects of fluid tilt on pressure measurements in practical scenarios.
USEFUL FOR

Students and professionals in engineering, physics, and fluid dynamics who are looking to deepen their understanding of pressure variations in fluid systems, particularly in tilted configurations.

Homework Statement


A 0.3 m long tube is filled with sterile solution of density 1037 kg m-3 and closed at the top. The tube is tilted at 40°. to the horizontal. The gauge pressure at the base of the tube is 3000 Pa. What is the gauge pressure at the top of the tube (in Pa)?

Homework Equations





The Attempt at a Solution



So I assumed that the tilting would have no effect so I just used pgh to find the weight of the fluid up until the bottom but that didnt even give me 3000 ... i got 3111
im really confused as how to how to respond to the change in angle.

cheers

The tilting would change the vertical height. It would be like a right angled triangle. I also think Bernoulli's equation would work here.
