Other Gas Power System Applications A combined gas turbine-vapor power plant operates as shown in Fig. P9.94. Pressure and temperature data are given at principal states, and the net power developed by the gas turbine is 147 MW. Using air-standard analysis for the gas turbine, determine

(a) the net power, in MW, developed by the power plant.

---

(b) the overall thermal efficiency of the plant.

Develop a full accounting of the net rate of exergy increase of the air passing through the gas turbine combustor. Let T0 = 300 K, p0 = 1 bar.
