SUMMARY

The discussion centers on calculating the force exerted by an oil-filled system on a cylinder at point A. The pressure at point A is determined using the formula P = Po + F/A, resulting in a pressure of 1.79 x 105 Pa. The key challenge identified is determining the vertical distance from the oil's surface to point A, which is crucial for accurate pressure calculations. Participants emphasize the importance of understanding pressure consistency across levels in fluid mechanics.

PREREQUISITES
  • Fluid mechanics principles, specifically hydrostatic pressure.
  • Understanding of pressure calculation formulas, including P = Po + F/A.
  • Basic knowledge of oil density and its impact on pressure.
  • Ability to interpret diagrams related to fluid systems.
NEXT STEPS
  • Study hydrostatic pressure calculations in fluid mechanics.
  • Learn about the properties of fluids, focusing on density and its effects on pressure.
  • Explore the concept of pressure distribution in static fluids.
  • Review case studies involving oil-filled systems and their applications in engineering.
USEFUL FOR

Students in engineering and physics, particularly those focusing on fluid mechanics, as well as professionals involved in designing and analyzing fluid systems.

In the figure(Figure 1)how much force does the fluid exert on the end of the cylinder at A?


Homework Equations

The Attempt at a Solution


[/B]
Solved for Poil using P = Po + F/A = 1.79 X 105. Simple enough.

Since pressure is the same across any level, we first have to first figure out the distance from Po to the top of A. This is where I am stuck. I feel like its something very simple but I just don't see it!

The distance is 70cm. We did this one in class, but I still don't see it.

You have to make an assumption based on the appearance.

This goes against everything I was ever taught, but as soon as you posted this it made sense. Thank you!
