Question 1.
What is the formula for pressure in a fluid?
Show hintHide hint
Remember that pressure depends on depth.
Question 2.
How does pressure change as you go deeper in a fluid?
Show hintHide hint
Think about the weight of fluid above.
3Question 3.
What happens to pressure as depth increases in a fluid?
- True
- False
Show hintHide hint
Think about what retains weight in a liquid.
4Question 4.
How is the resultant force on a submerged surface calculated?
Show hintHide hint
Use the formula F = PA.
Question 5.
Derive the formula for the center of pressure for an inclined plane and demonstrate it with an example where the plane is submerged at an angle of 30 degrees to the horizontal.
Show hintHide hint
Make sure to account for the angle in your calculations.
Question 6.
Evaluate the effect of varying fluid density on the resultant force experienced by a submerged plane area.
Show hintHide hint
Remember the relationship between pressure, density, and depth.
