1.4.3. Pressure Distribution Description

Try these first

1. 1.

   Define hydrostatic pressure in your own words.

   Hint

   Think about pressure as it relates to fluid depth.

2. 2.

   What is the formula for hydrostatic pressure?

   Hint

   Recall the variables involved in this equation.

3. 3.

   What is the hydrostatic pressure at a depth of 10 meters in water?

   • 9800 Pa
   • 10000 Pa
   • 20000 Pa

   Hint

   Remember the density of water and use the appropriate units.

4. 4.

   True or False: Capillarity causes liquids to rise in narrow tubes.

   • True
   • False

   Hint

   Think about how plants draw water from the ground.

5. 5.

   Calculate the force exerted by a rectangular plate measuring 2m by 4m submerged at a depth of 3m in water. Use g = 9.81 m/s² and ρ = 1000 kg/m³.

   Hint

   Use the pressure formula to find average pressure first.

6. 6.

   An inclined manometer reads a height difference of 0.2 meters when connected to a gas line. Calculate the gauge pressure, knowing the oil specific gravity is 0.9.

   Hint

   Use the height difference and oil's density for calculations.
