Challenge Problems
Push your limits with challenges.
Question 1
An engineer is designing a pipeline where water flows with a maximum velocity of 3 m/s. Calculate the Reynolds number, given the diameter is 0.2 m and dynamic viscosity is 0.001 Pa.s. Discuss if the flow will be laminar or turbulent.
💡 Hint: Use the formula for Reynolds number, adjusting values as necessary.
Question 2
Given the fluctuating velocity components in a turbulent flow as u'=0.5 m/s for the x-direction. If the density of the fluid is 1000 kg/m³, calculate the mass flux due to these fluctuations. Explain its importance in mass transport.
💡 Hint: Consider both mass and momentum interactions in turbulent flow.
