I'm trying to use the specific heat of water in an EMS program.
There are two built-in Erl functions, @CpCW (Cp for Chilled water) and @CpHW (Cp for Hot water) that accept an input parameter for temperature.
Except that as far as I understand from the source code here, both functions are exactly the same: they ignore the temperature passed to it and simply return 4180 J/kg-1.k-1. (I've tried using it, it's a constant 4180 indeed).
Am I missing something or is there just no function to get the specific heat at different temperatures?
