I'm just wondering how one would actually solve for the final enthalpy of air after entering a heat exchanger when the only known values are initial pressure and temperature before heating. I'm assuming that if air is modelled as an ideal gas you can just do (Cp)T, but how would you be able to find T in the first place? If the assumption of pressure changes being negligible, using the ideal has equations just leads to the final and initial temperatures being equal, unless I'm not doing it correctly.(adsbygoogle = window.adsbygoogle || []).push({});
