1.4.2. Flow Classification

Try these first

1. 1.

   Define a static fluid.

   Hint

   Think about the word 'static' in general.

2. 2.

   What is the equation for hydrostatic pressure?

   Hint

   Remember the variables relate to the conditions of a fluid in rest.

3. 3.

   What defines a static fluid?

   • A moving fluid
   • A fluid at rest
   • A compressible fluid

   Hint

   Think about the conditions of the fluid.

4. 4.

   True or False: The pressure increases with depth in a static fluid.

   • True
   • False

   Hint

   Consider the relationship of force and area.

5. 5.

   A rectangular dam gate measuring 6m by 4m is submerged. How do you calculate the force on it due to hydrostatic pressure?

   Hint

   Consider the average pressure due to the rectangle's submerged depth.

6. 6.

   An object submerged in a fluid is experiencing buoyancy. Determine how the angle of a triangular area affects the center of pressure.

   Hint

   Use geometric principles to discuss how pressure distribution changes.
