Interactive Quizzes
Engage in quick quizzes to reinforce what you've learned and check your comprehension.
Question 1
What is the primary reason shear stress is zero in a resting fluid?
- It acts parallel to the surface
- It is a function of velocity
- Fluid is not in motion
💡 Hint: Think about the conditions required for shear to occur.
Question 2
True or False: Gauge pressure is always positive.
- True
- False
💡 Hint: Consider what happens at low pressure levels.

Challenge Problems
Push your limits with challenges.
Question 1
A fluid at rest has a gauge pressure of 30 kPa at a depth of 2 m. Calculate the absolute pressure considering atmospheric pressure is 101.3 kPa.
💡 Hint: Remember to sum both pressures to find the absolute pressure.
Question 2
Using the Taylor series, approximate the pressure at a point P(3, 2, 1) knowing P(2, 2, 1) = 100 kPa and the pressure gradient in the x direction is 5 kPa/m.
💡 Hint: Consider how Taylor series expansions function when calculating nearby point values.
