Challenge Problems

Push your limits with challenges.

Question 1

A chemical engineer is designing a new pipeline system intended for a viscous liquid with a known viscosity of 0.005 Pa·s. The pipeline has a diameter of 0.15 m, and the liquid flows at 0.2 m/s. The density is 1200 kg/m³. Calculate the Reynolds number and determine if the flow is laminar or turbulent.

💡 Hint: Always check the flow regime after calculating.

Question 2

You are tasked with improving the mass transfer efficiency in a water treatment plant. Identify the effects of increasing flow velocity and how it affects the Reynolds number and turbulence, thereby influencing mass transfer efficiency.

💡 Hint: Think about the physical forces at play in fluid movement.
