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.

Try this example

{
  "ratio": 10,
  "gamma": 1.4,
  "cp": 1005,
  "cold": 300,
  "hot": 1200
}

Accuracy and scope

Ideal reversible compression/expansion, constant cp and γ, no pressure loss or regeneration. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
