A combined cycle gas turbine / vapor power plant uses the turbine exhaust as the energy source for the boiler. Each power system uses a single turbine. The gas power system is modeled as an ideal air-standard Brayton cycle. The vapor power system is modeled as an ideal Rankine cycle. Given specific operating conditions determine the temperature and pressure at each state, the rate of heat transfer in the boiler, the power output of each turbine, and the overall efficiency....
