Question 1.
What is hydrostatic pressure?
Show hintHide hint
Consider how pressure changes with depth.
Question 2.
How does the pressure at a point depend on depth in a fluid?
Show hintHide hint
Remember the formula P = ρgh.
3Question 3.
What does hydrostatic pressure depend on?
- Depth
- Density
- Gravitational acceleration
- All of the above
Show hintHide hint
Think about the pressure equation P = ρgh.
4Question 4.
True or false: The center of pressure for a submerged surface is at its centroid.
- True
- False
Show hintHide hint
Consider how pressure varies with depth.
Question 5.
A square gate measuring 1.5 m x 1.5 m is fully submerged. If the water density is 1000 kg/m³ and the gravitational force is 9.81 m/s², calculate the force acting on the gate and the moment about the hinge.
Show hintHide hint
Calculate pressure at the midpoint and remember to consider the right distance for the moment.
Question 6.
Given a rectangular gate submerged 2 meters in water, how do you derive the necessary vertical force required for maintaining stability around the hinge?
Show hintHide hint
Set the counteracting moments around the hinge to zero.
