Pump & Pipeline Heat Transfer Calculations: Determining Head, Horsepower, & Temperature Profiles
A comprehensive example of calculating key parameters for an operating centrifugal pump, including head, horsepower, and temperature rise. Starting with the fluid flow rate, hydraulic efficiency, and pressure data, the calculation process determines the head and mass flow rate using the fluid’s density, derived from API gravity. The segment then walks through the conversion of shaft power to horsepower and kilowatts, and the calculation of temperature rise across the pump. Additionally, the methodology for determining the temperature profile of a buried crude oil pipeline is illustrated, focusing on iterative procedures to estimate the outlet temperature considering heat transfer rates, specific heat capacity, and overall heat transfer coefficients. These calculations are crucial for optimizing pump performance and ensuring accurate temperature management in pipeline operations.
