Web22 Dec 2024 · I believe that parameter is just to specify a reference point (like 0 degC on temperature scale) for the specific enthalpy. The actual change in the enthalpy (energy transfer) is based on the difference between two states, so the value at the reference doesn't really matter. The default value in this block is 420 kJ/kg, which is the value from ... Web22 May 2024 · Example: Frictionless Piston – Heat – Enthalpy Calculate the final temperature, if 3000 kJ of heat is added. A frictionless piston is used to provide a …
