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, ? = 1.2 kg/m3 and dynamic viscosity, ? = 1.8 x 10^-5 kg/m·s and kinematic viscosity,
ν = 1.516×10^-5 m2/s.
