Effect of Orifice Length-Diameter Ratio on Spray Characteristics
This is a 1930 NACA technical report, published by NASA's Technical Reports Server, presenting engineering test data for fuel injection and spray characteristics for engineers and researchers. Its pictures are dense grids of plotted line graphs on cream paper, with multiple labelled curves in grey and black, offering a designer a source of clean, structured chart layouts with tidy axis labels and numbered series.
