What is the t after the compressor

Question

Problem

The phenol in Problem 13.154 is used in a gasturbine cycle where we need the heating value (or the negative of the enthalpy of combustion at the temperature after the compressor).

a. What is the T after the compressor, assuming a simple adiabatic compression from 100 kPa to 1.2 MPa?

b. Find H_RP = H_P - H_R, both at that T, except that phenol is liquid at 100?C.

Problem 13.154

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^oC. 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).

The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
