Design a steam power cycle that can achieve a cycle thermal efficiency of at least 40 percent under the conditions that all turbines have isentropic efficiencies of 85 percent and all pumps have isentropic efficiencies of 60 percent. Prepare an engineering report describing your design. Your design report must include, but is not limited to, the following:

(a) Discussion 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 labeled states and temperature, pressure, enthalpy, and entropy information for your design.

(c) Sample calculations.
