Damien,
The easiest way to add or removed energy from a liquid stream is with
the equation Tout = Tin + q/mdot/Cp.
I'd save the Excel data into a text file, read it with a Type9 data
reader and pass the result into the equation. Energy addition to the
liquid stream would be a positive value of q. Energy removal would be a
negative value.
Best,
David
