8.3.3. Integration of Pressure Functions

Try these first

1. 1.

   Define Control Volume in fluid mechanics.

   Hint

   Think about the space where fluid flow is studied.

2. 2.

   What happens to shear stress in static fluids?

   Hint

   Consider the conditions for a fluid in rest.

3. 3.

   What does a control volume in fluid mechanics represent?

   • A mere surface
   • A defined space for analysis
   • An abstract concept

   Hint

   Remember, it's a space where we analyze fluid behavior.

4. 4.

   True or False: Shear stress is present in static fluids.

   • True
   • False

   Hint

   Consider what happens to fluids at rest.

5. 5.

   A control volume contains water at a depth of 10 m. Calculate the gauge pressure at the bottom if atmospheric pressure is 101 kPa.

   Hint

   Use the water density and gravity in your calculations.

6. 6.

   In a barometric experiment, the height of mercury in the tube is 760 mm. What is the absolute atmospheric pressure?

   Hint

   Convert mm to meters for calculation.
