SUMMARY
This discussion focuses on calculating the specific enthalpy of air at varying temperatures and pressures, specifically at 200 kPa and 90 kPa. The user inquires about the use of thermodynamic tables, noting a lack of specific data for air at the desired pressures. The consensus is that for small temperature ranges, the specific heat capacity (Cp) can be utilized as an approximation for calculating enthalpy changes in ideal gases.
