Challenge Problems
Push your limits with advanced challenges
Given a fluid with a viscosity of 1 mPa.s and a density of 1000 kg/m³ flowing over a flat plate with a length of 5 m, what is the boundary layer thickness at the trailing edge if the free stream velocity is 2 m/s?
💡 Hint: Apply the appropriate formulas for boundary layer thickness using the free stream conditions.
Discuss the implications of increased boundary layer thickness on the drag force acting on an object moving through a fluid.
💡 Hint: Consider how this might affect performance in engineering designs.
