In a thermal power plant, an adiabatic steam turbine operating at steady state with inlet conditions at pressure of 30 bar, temperature of 350°C and mass flow rate of 10 kg/s. Half of the steam is extracted at the first exit at pressure of 5 bar and temperature of 200°C. The remaining steam leaves the second exit at pressure of 0.15 bar and a quality of 0.9. Neglect the change in kinetic and potential energy and the surroundings is assumed to be a temperature of 25°C and atmospheric pressure. Determine: a) The total work produced by the turbine (in kW) b) The exergy destruction (in kW)

In a thermal power plant, an adiabatic steam turbine operating at steady state with inlet conditions at pressure of 30 bar, temperature of 350°C and mass flow rate of 10 kg/s. Half of the steam is extracted at the first exit at pressure of 5 bar and temperature of 200°C. The remaining steam leaves the second exit at pressure of 0.15 bar and a quality of 0.9. Neglect the change in kinetic and potential energy and the surroundings is assumed to be a temperature of 25°C and atmospheric pressure. Determine: a) The total work produced by the turbine (in kW) b) The exergy destruction (in kW) c) The second law efficiency of the turbine d) It is proposed to modify the turbine blade in order to increase the performance of the steam turbine. With this modification, the steam conditions at the inlet and the first exit remain the same but the steam will leave the second exit at pressure of 0.1 bar and a quality of 0.9. Perform an appropriate analysis and justify whether it is worth considering such modification.
