Challenge Problems
Push your limits with challenges.
Question 1
Consider a pipe with a diameter of 2 cm. If water flows through it at a velocity of 3 m/s, calculate the Reynolds number and determine whether the flow is laminar or turbulent.
💡 Hint: Keep in mind the critical thresholds for laminar and turbulent flow.
Question 2
A short pipe with a 4 cm diameter has a length of 1 m. If the flow is classified as laminar, calculate the entrance length using the formula le/D = 0.06 Re. Assume the flow rate gives a Reynolds number of 500.
💡 Hint: Double-check your units and calculations for accuracy.
