(Berlin, Haude et Spener, 1754) 4to. No wrappers, as issued in "Mémoires de l'Academie Royale des Sciences et Belles-Lettres", tome VIII, Année 1752. Pp. 149-184 and 1 folded engraved plates. First appearance of an importent work on different kinds of water-pumps, analyzing their different amounts of force used."Euler also investigated a number of concrete problems on the motion of liquids and gases in pipes, on vibration of air in pipes, and on propagation of sound. Along with this, he worked on problems of hydrotechnology, discussed, in part, above. Especially remarkable were the improvements he introduced into the design of a hydraulic machine imagined by Segner in 1749 and the theory of hydraulic turbines, which he created in accordance with the principle of action and reaction (1752-1761)."(DSB).Eneström E 207.…
