Consider a rectangular flat plate placed horizontally parallel to an airflow of speed 30m/s. The flat plate is 2m long and 3m wide and the incoming free stream has standard conditions of density p = 1.2 kgm and kinematic viscosity of v= 1.5 x 10-5ms 1. A boundary layer (BL) of local thickness 8 = 8(x) develops along the plate's length. Assume a fully turbulent boundary layer. Calculate the following: (i) (iii) (iv) (v) The Reynolds number based on the plate's length the boundary layer thickness at the end of the plate the displacement thickness at the end of the plate the friction drag due to BL on both sides of the plate the BL shape factor (2 marks) (2 marks) (2 marks) (4 marks) (1 marks)
