The results of investigations relative to formulas for the flow of water in pipes
An 1890 engineering paper by hydraulic engineer Edmund B. Brownell Weston, published in New York for civil engineers comparing formulas for water flow in pipes. The plates are lettered line graphs on tinted stock: ruled grids, solid, dashed and dot-dash curves, diamond data points and rotated hand-drawn labels, useful as period chart texture and technical line vocabulary.
