The Cordier diagram represents a universally valid relationship between flow rate, pressure drop, runner diameter and runner speed of a fluid-flow machine Later contributions to Cordier’s theory suggest that there is not only a single Cordier curve, but rather a set of curves at which all design points of a fluid-flow machine are located ....

The second half of the book commences with an exhaustive collection of information on random diagrams, especially those whose sites are generated by a Poisson process Readers learn, for example, that a typical three-dimensional Voronoi cell has constant complexity: approximately 16 faces, 41 edges, and 27 vertic...
