Impeller Reynolds Number - an overview ScienceDirect Topics
Witryna5 lis 2024 · Pump efficiency is the “water horsepower” divided by the “brake horsepower” and multiplied by 100 to present it as a percentage (see formulas in Image 1). Water horsepower is a system design tool and is the power that the pump would require to accomplish the hydraulic conditions if it was 100 percent efficient. WitrynaA parameter used to characterise fluid flow is the Reynolds number. For full flow in pipes with circular cross-section, the Reynolds number Re is defined as: (7.1) where … sustainability aspects 意味
