Phenol, C₆H₅OH (M = 94.11 kg/kmol, C_P = 1.7 kJ/kg-K), is used in a combustion process being burned with stoichiometric air. The reactants are supplied at 1.21 MPa, the air at T₀ and the phenol as liquid at 100◦C. Enough heat transfer, Q₁, takes place after the combustion so that the products reach 1500 K. After the heat transfer the products are send through a turbine, where they expand to 120 kPa.

a. Find the heat transfer, Q1 (kJ/kmol fuel).

b. Find the enthalpy of formation of the fuel as vapor.

c. Find the specific turbine work output, W (kJ/kmol fuel).
