The calculations, reports, and estimations generated by this tool are intended exclusively for preliminary planning and educational purposes. While we utilize thermodynamic formulas matching IAPWS guidelines, variations in piping layouts, system curves, control valve drops, and elevation differences must be evaluated separately.
This calculator does not substitute for professional mechanical engineering consultation. Prior to purchasing or deploying any boiler feedwater pump, the results must be verified and signed off by a licensed Professional Engineer (PE) who is familiar with your plant's specific piping design.
Under no circumstances shall the operators, authors, or hosting providers of this website be liable for any direct, indirect, incidental, or consequential damages (including, but not limited to, equipment failure, plant downtime, or safety incidents) arising from the use or reliance on calculations obtained from this tool.
The underlying physics algorithms, density interpolation schemas, and client-side codebases are provided on an open-source basis. You are free to copy, modify, and distribute the sizing algorithms for commercial or private projects.
