Challenge Problems

Push your limits with challenges.

Question 1

In a pipe flowing with a fluid where the velocity decreases towards the pipe walls, calculate the momentum flux using both the average velocity and incorporating the appropriate correction factor. Given: Average velocity is 3 m/s, correction factor is 1.5.

💡 Hint: Make sure to identify the fluid's density to finalize the computations.

Question 2

Explore a practical scenario where ignoring atmospheric pressure in a control volume could lead to significant errors in fluid dynamics calculations. Describe how you would correct this mistake.

💡 Hint: Consider examples like open tank dynamics or atmospheric discharge from pipes.
