WebSummary. For an ideal gas, the molar capacity at constant pressure Cp C p is given by Cp = CV +R = dR/2+ R C p = C V + R = d R / 2 + R, where d is the number of degrees of freedom of each molecule/entity in the system. A real gas has a specific heat close to but a little bit higher than that of the corresponding ideal gas with Cp ≃CV +R. Webmore about gases and specific heats The enthalpy in a fluid is defined as: h = u + p / ρ (3) where h = enthalpy (kJ/kg) u = internal energy (kJ/kg) p = absolute pressure (Pa) ρ = density (kg/m3) Combining (3) and the Ideal Gas Law: h = u + R T (4) where R = the individual gas constant (kJ/kgK)
