Hi,

When calculating the temperature difference, measured by "measure units" in the inlet and outlet of a heat exchanger:

Hot (h) equals 140C, Cold (c) 40.2C and the result from the calculator, h-c is -173C!

see attached fsd

You specified the unit of measure of the output as an absolute temperature. Please edit the information calculator, click the >> after Output, and check the relative box in the bottom, which makes the unit of measure of the output a temprature difference. Now the 273.15 offset between C and K is no longer used by COFE.

Note that you must disconnect and reconnect stream 45 after that for stream 45 itself to get reconfigured.
