Challenge Problems
Push your limits with advanced challenges
A liquid with a density of 850 kg/m³ flows through a pipe with a diameter of 0.05 m at an average velocity of 1.5 m/s. Calculate the Reynolds number and determine if the flow is laminar or turbulent.
💡 Hint: Ensure you use the correct relationship for viscosity.
How would decreasing the flow velocity in a piping system impact the flow regime? Discuss the transition from turbulent to laminar flow.
💡 Hint: Consider how flow velocities affect the Reynolds number's value.
