8.1.2. Forces Acting on the Control Volume

Try these first

1. 1.

   Define 'Control Volume'.

   Hint

   Think about a volume that has fluid flowing in and out.

2. 2.

   What is gauge pressure?

   Hint

   It’s the pressure you feel when you inflate a tire.

3. 3.

   What is a control volume?

   • A fluid flowing region
   • An incompressible fluid
   • A region with no forces

   Hint

   It's a concept in fluid dynamics.

4. 4.

   True or False: Pressure acts parallel to fluid surfaces.

   • True
   • False

   Hint

   Think about how fluids behave under pressure.

5. 5.

   Calculate the gauge pressure at a depth of 10 meters in water. Given density (ρ) of water is 1000 kg/m³ and g = 9.81 m/s².

   Hint

   Apply the basic hydrostatic pressure formula.

6. 6.

   Explain how the concepts of gauge versus absolute pressure apply in high-altitude environments, such as mountain climbing.

   Hint

   Consider how gases behave with change in elevation.
