(10pts) A power plant can be described by an ideal Rankine cycle without any irreversibility's. he boiler produces superheated steam at a pressure of 200 bars and temperature of 600c (1). The steam expands adiabatically (and isentropicly) thru a turbine exiting as a saturated vapor/liquid mixture at pressure of 0.1bar (2). The mixture passes thru a condenser (P-0.1bar) until it is all saturated liquid (3). It is then pumped adiabatically to...
