Heat Exchanger Duty
Q = ṁ cp (T_out − T_in) for a single fluid stream (water, glycol, air, process).
Thermal & HVACFluid & Pressure
Q = ṁ cp (T_out − T_in) for a single fluid stream (water, glycol, air, process).

How to fill it
Fill the inputs. The tool shows the outputs.
On the tool screen, Calc is the working sheet. Presets stores values you reuse. Reference is the formula, assumptions, and provenance below.

Diagnose
This tool does not attach diagnose observations.
Assumptions
- cp is constant. No phase change — use THERM-05 for latent.
Provenance
- Heat added to the stream is positive. Cooling a stream gives a negative duty.
