Question 1.
What is hydrostatic pressure?
Show hintHide hint
Think about how pressure changes with depth.
Question 2.
How does pressure act on a horizontal surface?
Show hintHide hint
Consider the formula for pressure.
3Question 3.
What is the formula for hydrostatic pressure?
- P = P_{atm} + ho g h
- P = ho g h
- P = P_{atm} - ho g h
Show hintHide hint
Think about the components that contribute to total pressure.
4Question 4.
True or False: The center of pressure is always located above the centroid of a submerged surface.
- True
- False
Show hintHide hint
Consider the distribution of pressure on the surface.
5Question 5.
A large cylindrical tank is filled with water 10 meters deep. Calculate the hydrostatic pressure at a point 8 meters below the surface and the total force acting on the curved surface of the cylinder.
- Assume diameter is 4 meters.
Show hintHide hint
Remember to find the area of the curved surface and include atmospheric pressure in your calculations.
6Question 6.
A vertical gate measuring 3m x 2m is submerged in water at a depth of 6 meters. Determine the center of pressure and the total hydrostatic force on the gate.
- What is the formula used and how do we relate the center of pressure to its centroid?
Show hintHide hint
Consider the relationship between depth, area, and pressure distribution.
