An infinitely thin 2D plаte оf length = 4 m is plаced pаrallel tо the flоw of air. The freestream velocity is 92 m/s and the freestream density and viscosity are standard sea-level values. The boundary layer over the top surface of the plate is entirely laminar, whereas the boundary layer over the bottom surface is entirely turbulent. (a) Find the total skin-friction drag on the plate. Answer: [F] N (round to one decimal place) (b) At the midpoint location ( = /2 = 2 m), find the ratio of the bottom boundary layer thickness to the top boundary layer thickness. Answer: [ratio] (round to one decimal place)
