Pp. 311-354 and 5 folded engraved plates. <br/><br/><em>First edition. In this importent paper Euler perfection Segner's hydraulic turbine giving the theory of hydraulic turbines created in accordence with the principle of action and reaction."In this work Euler gives a complete hydraulic analysis an early example of the theory of relative motion. He also shows that very high speeds are necessary for good efficiency. He argues that "by means of fixed conducting tubes adjust the incoming velocity of the water so that the speed of efflux relative to the rotor is zero;" in this way the theorietical efficiency will be "100% at the desired speed of operation.""Truesdell.Enestroem: 179. </em> unknown
