Design a steam power plant that is efficient.

  1. Design a steam power cycle that can achieve a cycle efficiency of at least 40 percent under conditions that all turbines have isentropic efficiencies of 80 percent and all pumps have isentropic efficiencies of 65 percent. Prepare an engineering report describing your design. Your design should include the following, a. Discussions of various cycles attempted to meet the goal as well as the positive and negative aspects of your design. b. System figures and T-s diagrams with labelled states and temperatu enthalpy and entropy information for your design. c. Show at least one sample calculation for each new system implemented. d. If you are using programming language for the generation of more data, you are expected to attach the code or programme as an appendix. Programmes such as MATLAB, EXCEL and EES (Engineering Equation Solver) might be used for this purpose. 2. Early commercial vapor power plants operated with turbine inlet conditions of about 12 bar and 200oC. Plants are under development today that can operate at over 34 MPa, with turbine inlet temperatures of 650oC or higher. How have steam generator or turbine designs changed over the years to allow for such increases in pressure and temperature? Discuss. (800 -1500 words maximum)
