				| 1. | The average drag coefficient for turbulent boundary layer flow past a thin plate is given byCf = 0.455/ (log10 Rel)^2.58Where R el is the Reynolds number based on plate length. A plate 50 cm wide and 5 m long is kept parallel to the flow of water with free stream velocity 3 m/s. Calculate the drag force on both sides of the plate. For water, kinematic viscosity = 0.01 stokes |
