1.1.2. Fluid Statics Applications: Example Problems

Try these first

1. 1.

   Define hydrostatic pressure.

   Hint

   Think about fluids and their weight.

2. 2.

   What is the formula for calculating pressure in a fluid?

   Hint

   Consider fluid density, gravity, and height.

3. 3.

   What is hydrostatic pressure calculated from?

   • Velocity and density
   • Density
   • gravity
   • height
   • Pressure and area

   Hint

   Remember the equation P = ρgh.

4. 4.

   True or False: Buoyancy is always equal to the weight of the submerged fluid.

   • True
   • False

   Hint

   Consider what happens when an object is placed in water.

5. 5.

   A gate of height 1 meter has water exerting pressure on it at various depths. Calculate the total force acting on the gate and locate the position where this force acts.

   Hint

   Remember pressure is depth-dependent, calculate forces accordingly.

6. 6.

   A manometer connected to a gas pipe shows a 150 mm rise with mercury of specific gravity 13.6. Calculate the pressure in the gas line.

   Hint

   Use the relationship between heights and pressure differences.
