A steam power plant design consists of an ideal Rankine cycle with reheat and regeneration. Steam enters Turbine 1 at P1 and T1 at the rate of m1 and exits at P2. A fraction (y') of the steam exiting Turbine 1 is diverted to a closed feedwater heater while the remainder is reheated to T3 before entering Turbine 2. A fraction (y'') of the steam exiting Turbine 2 at P4 is diverted to an open feedwater heater while the remainder...
