Simple reheat Rankine cycle in a steam power plant

Assume that the surroundings are at 298 K, the kinetic and potential eneigy changes are negligible, and this is a steady process. 

Because this is an isentropic process S3 =. S 4 and. S) = S2. We estimate the quality of the discharged wet steam (S3jV . V4 v) after passing through the turbine

Example 4.13 Simple reheat Rankine cycle in a steam power plant A simple ideal reheat Rankine cycle is used in a steam power plant (see Figure 4.19). Steam enters the turbine at 9000kPa and 823.15 K and leaves at 4350kPa. The steam is reheated at constant pressure to 823.15K. The discharged steam from the low-pressure turbine is at 10 kPa. The net power output of the turbine is 65 MW. Determine the thermal efficiency and the work loss at each unit.
