Challenge Problems
Push your limits with challenges.
Question 1
Given the velocity field of a fluid in a pipe, calculate the pressure drop across a distance of 10 meters if the velocity varies linearly from 2 m/s to 5 m/s.
💡 Hint: Think about how pressure influences velocity and vice versa.
Question 2
In a scenario where a gas flows through a narrowing pipe section, explain how the pressure and density change, especially when the Mach number exceeds 0.3.
💡 Hint: Remember the relationship between pressure, velocity, and density in compressible flow.
