Challenge Problems

Push your limits with challenges.

Question 1

A fluid with a density of 1000 kg/m^3, dynamic viscosity of 0.001 Pa.s, and a velocity of 5 m/s is flowing over a length of 2 m. Calculate the Reynolds number and determine the type of flow.

💡 Hint: Use the formula for Reynolds number carefully.

Question 2

A rectangular plate measuring 1 m by 0.5 m is submerged in water at 20°C with a viscosity of 0.001 Pa.s. If the top surface of the plate experiences a velocity of 2 m/s, calculate the boundary layer thickness at the end of the plate assuming it is a steady flow.

💡 Hint: Research boundary layer approximations to derive the solution.
