عنوان انگلیسی: Understand the Fundamentals of Centrifugal Pumps چکیده انگلیسی: Abstract: Several factors that need to be considered by chemical engineers when selecting radial-flow centrifugal pumps are presented. The first step in determining whether a pump will meet the process requirements is to review the pump performance curves. The diagram depicts the relationships between volumetric flowrate and total dynamic head, efficiency, required net positive suction head (NPSHR), and required power. The preferred operating region is between 70% and 120% of the best efficiency point (BEP) flowrate (J), although most users require the rated flow to fall between 80% and 110% of the BEP. A centrifugal pump increases the absolute pressure of a fluid by adding velocity energy to the fluid and then converting that to head energy
