Flow and Drag Formulas for Simple Quadrics
This is a 1927 NASA technical report, collected by the NASA Technical Reports Server, that gives flow and drag formulas for simple quadric shapes such as cylinders and ellipses in a frictionless fluid. The pictures are engineering plots and diagrams: velocity and pressure curves around a cylinder and elliptical section, streamline sketches with constant-speed hyperbolas, and a drag coefficient chart against Reynolds number on log axes. A designer could take from them the clean line-and-dot plotting style and the streamline diagrams as a model for technical figures.
