Engineering calculator reviewed for preliminary design use · Last updated: March 2026
EngiCompute provides a comprehensive suite of engineering calculation tools for process and mechanical design. Our calculators cover fluid mechanics, thermodynamics, pressure vessel design, piping, and more. All tools are free, browser-based, and designed for plant engineers, process engineers, and students.
For preliminary estimation and educational use only. Results may depend strongly on assumptions, input data, fluid or material properties, and the range of validity of the underlying equation. Verify critical calculations independently and follow the applicable code, specification, and formal engineering review process before using any result for design, procurement, fabrication, operation, or safety decisions.
