Extracted text: Question 2 Air at 20 °C flows at V = 10 m/s over a flat plate of length L= 1.52 m and width W = 2 m. Calculate the boundary layer thickness at the trailing edge of plate and drag force on one side of plate if: a. Surface of plate is smooth. b. Surface of plate is rough. The air properties at 20 °C are: Density, p = 1.2 kg/m³ and dynamic viscosity, u= 1.8x 105 kg/m s and kinematic viscosity, v = 1.516x10 m /s. www www
