The transference of heat from a hot plate to an air stream
A 1931 NACA technical memorandum from the NASA Technical Reports Server, issued by the National Advisory Committee for Aeronautics, on heat transfer from a heated plate to a moving air stream. The pages are numbered figures and charts, rotated sideways on the scan, meant for engineers working in aerodynamics and thermal analysis. A designer could take the restrained, grid-based graph layouts, the tabulated data blocks beside each curve, and the clean black linework on white paper as a model for technical diagrams.
