Can you please solve the question b, c, d and e for me please?
Given that:
Task 3 (21) In a heat recovery boiler (steam generator), the exhaust gases of a gas turbine process are used to evaporate water in an isobaric steam power process at the pressure pa = 10 MPa. During this process, the temperature of the water increases from t2 = 28 C to 3=510 C. The superheated steam is then expanded into the wet steam region and to the condenser pressure p = 0.006 MPa via an irreversible adiabatic turbine (1.1 = 90%). The isobaric condenser supercools the liquid by AT = 10 K before it is fed to the irreversibly adiabatic boiler feed pump. The exhaust gases of the gas turbine process enter the isobaric boiler with the mass flow ritesh = 380 kg/s at a temperature of tes = 520 C, and leave it with the temperature tout = 190 C. The exhaust gases can be considered ideal gases with a constant heat capacity of Cpath = 1.31 kJ/(kg.K). Exhaust gas with a Exhaust gas with boiler 3 P 1 condenser a) Illustrate a qualitatively correct T-s-diagram of the steam power process. (3) b) Determine the mass flow m, circulating in the steam power process. c) Determine the effective (useful) power of the steam power process Pae (8) d) Determine the thermal efficiency np.comb for the combined process of gas and steam tur- bine, in the case of Px.cz=-113.7 MW and Trib.G1 = 34.4% for the gas turbine process. (2) e) Determine the exergy loss AE, in the hear recovery boiler for an ambient temperature of to = 20 C.
