Challenge Problems
Push your limits with advanced challenges
Given a pipe radius of R = 0.5 m, find the maximum and average velocity if the profile defined is $u(r) = u_{max}(1 - \frac{r}{R})^{\frac{1}{7}}$ with $u_{max} = 10 m/s.$
💡 Hint: Break it down by simplifying the integration process and referencing the derived formulas.
Explain why the wall shear stress cannot be calculated using the power law velocity profile at the boundary, and provide a mathematical basis for your reasoning.
💡 Hint: Investigate the implications of derivatives as you approach the pipe's wall in calculations.
