8.3. Pressure Distribution Equations

Try these first

1. 1.

   Define gauge pressure.

   Hint

   Think about how we compare pressures above and below the atmosphere.

2. 2.

   What is a control volume?

   Hint

   Recall that we analyze forces and pressure within a specific area.

3. 3.

   What does Pascal's Law state?

   • Pressure is constant
   • Pressure increases with depth
   • Pressure transmitted in all directions is constant

   Hint

   Think about how pressure behaves in a closed container.

4. 4.

   True or False: Gauge pressure is always negative.

   • True
   • False

   Hint

   Consider the context of gauge pressure compared to atmospheric pressure.

5. 5.

   A tank is filled with two fluids: water (density = 1000 kg/m³) and oil (density = 800 kg/m³), with water on top. If the height of water is 5m and oil is 3m, calculate the pressure at the bottom of the tank.

   Hint

   Calculate each pressure contribution separately before summing them.

6. 6.

   In a fluid static equilibrium situation, if the height of water above a point is 12m, what is the gauge pressure in kPa?

   Hint

   Convert your final answer into kPa for clarity.
