7/26/2023 0 Comments Viscosity index calculation![]() The initial purchase price of a pump is only a small fraction of the total lifecycle cost. In industrial operations, pumping alone can account for between 25 and 50% of the total energy usage of the process, depending on the application. ![]() Chemical engineering literature does not fully cover other essential aspects of pump sizing and selection - including the viscosity correction, power consumption, commercial availability and lifecycle cost analysis. ![]() A number of recent articles provide useful guidelines for sizing and selecting pumps, but these articles focus on certain specific aspects of proper pump sizing, while leaving out others. Many aspiring chemical engineers enter industry after university study without sufficient practical knowledge about how to properly size pumps. An automated spreadsheet method helps engineers take those factors into account in centrifugal pump selection Viscosity, power consumption, commercial availability and lifecycle cost analysis are all important considerations in pump sizing.
