Question 1.
What is hydrostatic pressure?
Show hintHide hint
Refer to the formula P = ρgh.
Question 2.
How does pressure change with depth?
Show hintHide hint
Use the formula for hydrostatic pressure to illustrate.
3Question 3.
What is the formula representing hydrostatic pressure?
- P = ρg
- P = ρgh
- P = g/ρ
Show hintHide hint
Remember the parameters involved in calculating pressure.
4Question 4.
Is the moment about a hinge of a stationary gate always zero?
- True
- False
Show hintHide hint
Consider what equilibrium means for forces and moments.
Question 5.
A cylindrical gate of height 3 meters and radius 1 meter is fully submerged. Calculate the total force acting on the gate and the moment about the hinge at the bottom.
Show hintHide hint
Consider the areas and how pressure varies with depth.
Question 6.
For a semi-cylindrical gate with a diameter of 2 meters submerged to a depth of 4 meters, determine the force needing to balance both horizontal and vertical components to maintain equilibrium.
