Actual reheat Rankine cycle in steam power generation

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

Because this is an isentiopic process S3 = S4s and. S, = S2s, S3V S6 V we estimate the quality of the discharged wet steam after passing through the turbine

Example 4.14 Actual reheat Rankine cycle in steam power generation A reheat Rankine cycle is used in a steam power plant (see Figure 4.20). Steam enters the high-pressure turbine at 9000kPa and 823.15K and leaves at 4350kPa. The steam is reheated at constant pressure to 823.15 K. The steam enters the low-pressure turbine at 4350kPa and 823.15K. The discharged steam from the low-pressure turbine is at lOkPa. The net power output of the turbine is 65 MW. The isentropic turbine efficiency is 80%. The pump efficiency is 95%. Determine ...
