Challenge Problems
Push your limits with challenges.
Question 1
A pipe has a diameter of 0.2 m, and the average velocity of the fluid is 1 m/s. Calculate the Reynolds number if the dynamic viscosity is 0.001 Pa.s. Discuss whether the flow is laminar or turbulent.
💡 Hint: Plug in the values carefully.
Question 2
If the turbulent flow in a pipe exhibits a fluctuating velocity component of 0.5 m/s, calculate the additional momentum flux caused by this fluctuation in a cross-sectional area of 0.1 m².
💡 Hint: Remember the mass flux formula and apply it for momentum.
