Atomization of liquid fuels. Part III
A 1925 NACA technical memorandum from the NASA Technical Reports Server, the third part of a study on how liquid fuels break into droplets when sprayed. Its pages are mostly engineering graphs plotting drop diameter against discharge velocity and atomization pressure, with curves for gas-oil and kerosene. A designer might take from them the clean, dense grid layouts, labelled axes and hand-drawn curve families as a source for technical chart styling.
