Question:
Consider a MW steam power plant that operates on a nonideal Rankine cycle
an isentropic efficiency of for both the turbine and the pump Steam enters the turbine at MPa and oC and is cooled in the condenser at a pressure of kPa.
a Assume the power plant discharges energy by heat transfer to the condenser
and the cooling water is at an average temperature of oC and determine the
maximum theoretical thermal efficiency.
b Explain why the actual cycle thermal efficiency is considerably less than the
maximum theoretical thermal efficiency.
c Redesign the steam power cycle that can achieve an actual cycle thermal
efficiency of at least
