Closure to “Discussion of ‘Volute Pressure Distribution, Radial Force on the Impeller, and Volute Mixing Losses of a Radial Flow Centrifugal Pump’” (1960, ASME J. Eng. Power, 82, pp. 143–144)

Abstract

volute results from a mechanical-energy balance on an element of the volute as in Fig. 10. For the element, the mechanicalenergy rate loss is the difference between the energy-rate input and the energy-rate output, or, dEm = 0 P + P tM('
