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. --Given Values--...

8.11 Plot each of the quantities calculated in Problem 8.10 versus condenser pressure ranging from 0.3 lbf/in. to 14.7 lbf/in.? Maintain constant net power output. Discuss. (a) Use condenser pressure of 2.0 lbf/in? (already solved in problem 10) (b) Use condenser pressure of 14.696 lbf/in?. (Solve the problem only for these two pressures and then for your graphs, connect the two dots. Because each graph will only have two dots, instead of a curve your graphs will be straight lines.)...
