Challenge Problems
Push your limits with challenges.
Question 1
A fluid's velocity reduces from 10 m/s to 2 m/s over a distance of 5m. Calculate the shear stress on the boundary if the fluid's viscosity is 0.02 Pa.s.
💡 Hint: Use the formula for shear stress with the average gradient.
Question 2
Determine if a fluid with a Reynolds number of 200,000 is in a laminar, transitional, or turbulent state.
💡 Hint: Reference Reynolds number thresholds for flow states.
