How to use this tool

  1. Enter every input in the labeled units; use measured or independently specified properties.
  2. Check the stated model assumptions before calculating.
  3. Interpret the output as a model estimate and verify it independently for the intended application.

Accuracy and scope

Quasi-equilibrium polytropic path; positive work denotes expansion. No heat-transfer inference without gas properties. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
