Challenge Problems
Push your limits with challenges.
Question 1
A fluid has a density of 1000 kg/m³ and a dynamic viscosity of 0.001 Pa.s. Calculate the Reynolds number for a pipe with a diameter of 0.05 m and a fluid velocity of 2 m/s. Discuss whether the flow is laminar or turbulent.
💡 Hint: Use the Reynolds number formula to perform your calculations.
Question 2
In an open channel flow with an average flow depth of 0.5 m and a velocity of 3 m/s, calculate the Froude number. Discuss the implications of the result on flow classification.
💡 Hint: Recalling the definition of the Froude number will help you calculate.
