8.7. Conclusion

Try these first

1. 1.

   What happens to shear stress in a fluid at rest?

   Hint

   Think about the motion of a fluid.

2. 2.

   What is absolute pressure?

   Hint

   Consider where you start your measurement.

3. 3.

   What is the primary force acting on a fluid at rest?

   • Pressure
   • Shear Stress
   • Friction

   Hint

   Think about how pressure operates in fluids.

4. 4.

   True or False: Gauge pressure is always higher than absolute pressure.

   • True
   • False

   Hint

   Consider different scenarios when these pressures are measured.

5. 5.

   A fluid is at rest in a tall cylindrical tank. Calculate the pressure at the bottom of the tank if the fluid has a density of 1000 kg/m³ and a height of 5 meters.

   Hint

   Don't forget to include the gravitational acceleration.

6. 6.

   Describe how pressure measurements would differ at sea level versus on a mountain peak.

   Hint

   Consider how altitude influences atmospheric pressure.
