Query: Euler Analysis of a Machine for Raising Waters Proposed by Mr. de Mour   We revisited an analysis made by Euler in a memoir of 1753 'Sur une nouvelle
maniere d'elever de l'eau propose par M. de Mour' (On a new method to raise

consisting of an inclined tube with its lower end immersed into water, and
discharging water at its top by turning a vertical axis to which the inclined
tube is attached.
