Understanding Water Pressure: Solving Homework with P1 and P2 Equations

Click For Summary
SUMMARY

The discussion focuses on solving a homework problem involving water pressure using the equations P2 = P1 + pgh. Participants clarify that P1 represents the pressure in chamber 1, while P2 is the pressure in chamber 2, given as 1.3x10^5 pascals. To find the force in chamber 1, users emphasize rearranging the formula for pressure (pressure = force/area) after calculating the pressure for chamber 1. This approach ensures accurate application of the principles of fluid mechanics.

PREREQUISITES
  • Understanding of fluid mechanics principles
  • Familiarity with the equation P2 = P1 + pgh
  • Knowledge of pressure calculations (pressure = force/area)
  • Basic algebra for rearranging equations
NEXT STEPS
  • Study the derivation and applications of the hydrostatic pressure equation
  • Learn about the implications of pressure in different fluid systems
  • Explore examples of force calculations in fluid mechanics
  • Investigate real-world applications of pressure equations in engineering
USEFUL FOR

Students studying physics, particularly those focusing on fluid mechanics, as well as educators looking for practical examples of pressure calculations in real-world scenarios.

Homework Equations



P2=P1+pgh

The Attempt at a Solution



I thought you would just plug in the pressure in pascals to p1 and add [(1000 kg/m3)(9.8m/s2)(sqrt 2)]?

Okay find out the pressure in chamber 1. Pressure=force/area.
Did this help?
 
So the answer is just 1.3x10^5 divided by 2?

Why?
 
No, 1.3x10^5 is pressure in chamber 2. Use the formula given to you in the question to calculate the pressure in chamber 1. You know the area of chamber 1 and you have calculated the pressure for chamber 1 so rearrange the formula pressure=force/area to give you the force.
