Challenge Problems
Push your limits with advanced challenges
A pipe has a diameter of 10 cm, and water flows at 3 m/s. The kinematic viscosity of water at this temperature is 0.001 m²/s. Determine the Reynolds number and classify the flow.
💡 Hint: Use the Re formula and check the conditions for flow classification.
In an industrial setup, oil is transported through a pipe with a diameter of 15 cm at 1 m/s. The oil has a kinematic viscosity of 0.05 m²/s. Calculate the Reynolds number and state whether the flow is laminar, turbulent, or transitional.
💡 Hint: Calculate using the formula and compare against the thresholds.
