The steam engine and turbine; a text-book for engineering colleges
A 1911 engineering textbook by Robert C. H. Heck, published by D. Van Nostrand in New York for American engineering students studying steam engines and turbines. The plates are line diagrams: pressure-volume and temperature-entropy curves, lettered construction points, axis scales in pounds per square foot and cubic feet, plus sectional machine drawings, useful as sparse technical linework and chart vocabulary.
