Question 1.
What is hydrostatic pressure?
Show hintHide hint
Think about the water weight above.
Question 2.
How does pressure change with depth in a fluid?
Show hintHide hint
Consider how much water is above a certain point.
3Question 3.
What happens to hydrostatic pressure as depth increases?
- It decreases
- It increases
- It stays the same
Show hintHide hint
Relate this to the weight of water.
4Question 4.
True or False: Center of pressure is located at the same point as the center of gravity for submerged surfaces.
- True
- False
Show hintHide hint
Think about how pressure changes with depth.
Question 5.
Calculate the total hydrostatic force on a vertical wall that is 3 m high submerged in water. Assume water density is 1000 kg/m³.
Show hintHide hint
Use the trapezoidal rule for approximation.
Question 6.
Analyze a case where a flat plate is submerged in three different fluids, with densities 1000 kg/m³, 950 kg/m³, and 850 kg/m³ at varying depths. How would you compute the resultant pressure?
Show hintHide hint
Consider the contributions from each fluid layer and sum them.
