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

{
  "h1": 200,
  "h2": 210,
  "h3": 3200,
  "h4": 2200,
  "flow": 2
}

Accuracy and scope

User supplies thermodynamically consistent enthalpies from independent property data; no steam-property calculation. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
