1.1.1. Lecture - 13

Try these first

1. 1.

   What is Pascal's Law?

   Hint

   Consider how pressure acts in all directions in a static fluid.

2. 2.

   What is the formula to calculate pressure at a depth in a fluid?

   Hint

   Think of what each symbol represents.

3. 3.

   What does Pascal's Law state?

   • Pressure is constant at any depth
   • Pressure increases with depth
   • Pressure varies with container shape

   Hint

   Think about the implications of pressure in different orientations.

4. 4.

   True or False: Hydrostatic pressure increases linearly with depth.

   • True
   • False

   Hint

   Consider how pressure acts below the surface of a liquid.

5. 5.

   A triangular gate submerged vertically in fluid has a base of 2 m and a height of 3 m. Calculate the resulting force acting on the gate.

   Hint

   Consider using the formula for triangular areas and integrate it alongside hydrostatic pressure principles.

6. 6.

   Determine the pressure difference measured in a manometer when the liquid column height is 150 mm and the fluid has a specific gravity of 0.9.

   Hint

   Use units carefully and make sure to consider the conversion metric of the specific gravity.
