You are required to determine several thermodynamic properties of hot steam in power plant. Some properties such as temperature, pressure, volume, density and mass are simply measure by direct measurements and equation. However, the properties such as internal energy, entropy and enthalpy have very limited data by using the thermodynamic table and simple relation. (i) In your opinion, why the internal energy, entropy and enthalpy are not simply measured. (ii) Suggest in details how you are able to determine the lacking information in thermodynamic properties of the hot steam in this power plant
