Challenge Problems
Push your limits with challenges.
Question 1
A fluid with a viscosity of 0.001 Pa·s flows through a 5 cm diameter pipe at a velocity of 1 m/s. Calculate the Reynolds number and determine if the flow is laminar or turbulent.
💡 Hint: Don't forget to convert units if needed.
Question 2
For flow through a circular pipe, derive the equation of velocity as a function of radius under laminar flow conditions. Consider the assumptions discussed.
💡 Hint: Start from the defined shear stress τ = -μ(du/dr), integrate considering boundary conditions.
