Nothing wrong with the suggestions, but I'd be wary of fudging physical properties as that may also alter things like pressure drop if the density isn't constant. You've accounted for the thermal mass by altering cp. nTo the OP, you may be better off explaining what you're doing over posting equations: we're very limited in what support we can offer (read the rules!) so can offer hints and suggestions only if it's not in the manual. n
