Pump Calculations: Determining Head, Shaft Power, and Temperature Rise

This segment reviews the detailed process of calculating key pump parameters, including head, shaft power, and temperature rise. It covers the essential steps to determine the shaft power in foot-pound force per second, conversion to horsepower and kilowatts, and the calculation of temperature rise due to inefficiencies in a centrifugal pump. By leveraging the specific gravity of the fluid, hydraulic efficiency, and detailed pressure data, the calculations provide a comprehensive understanding of pump performance. The example calculation walks through the process of determining the head from pressure rise, converting between units, and calculating the temperature change across the pump, ensuring precise and reliable results for pipeline operations.
