Velocity Distribution in the Boundary Layer of a Submerged Plate
This is a 1930 NACA technical memorandum issued by the National Advisory Committee for Aeronautics for aeronautical engineers and researchers, reporting measured velocity profiles in the boundary layer over a submerged plate. The pages are dense with graphs of experimental data, plotted curves and labelled figure numbers, along with a few photographs of wind-tunnel and test apparatus. A designer could draw on the plain black-and-white technical plotting style, the grid-based charts, and the clean engineering photographs of laboratory equipment.
