How to use this result.

Get the thermal driving force for exchanger rating.

Verify before relying.

  1. Confirm units match the input labels before trusting the result.
  2. Recompute at minimum and maximum operating cases, not just the design point.
Screening result for preliminary sizing only. Verify against the manufacturer datasheet and applicable standard before procurement or construction.
