Universal logarithmic law of velocity distribution as applied to the investigation of boundary layer and drag of streamline bodies at large Reynolds number
This is a 1937 NACA technical memorandum from NASA's Technical Reports Server, a scientific report on fluid dynamics for engineers and researchers. The page shows two rotated graphs plotting velocity data against logarithmic axes, with curves and data points, and a figure caption at the bottom. A designer might take its clean grid layout, thin dark curves and dotted data markers as a model for minimal technical charts.
