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

{
  "clean": 1000,
  "inside": 0.0002,
  "outside": 0.0003,
  "area": 10,
  "lmtd": 30
}

Accuracy and scope

All resistances use the same area basis; fixed LMTD comparison does not solve changed stream outlets. Educational engineering estimate only; not structural or safety certification, equipment selection, or operating recommendations.
