Hydraulics and Fluid Mechanics in ME The boundary layer thickness at a distance of l m from the leading edge of a flat plate, kept at zero angle of incidence to the flow direction, is O.l cm. The velocity outside the boundary layer is 25 ml sec. The boundary layer thickness at a distance of 4 m is (Assume that boundary layer is entirely laminar) 0.20 cm 0.10 cm 0.05 cm 0.40 cm 0.20 cm 0.10 cm 0.05 cm 0.40 cm ANSWER DOWNLOAD EXAMIANS APP
