only do part B) please Thank you!

Extracted text: In an ideal steam regenerative Rankine cycle with two feedwater heaters, one closed and one open, steam enters the turbine at 12.5 MPa and 550°C. Steam is extracted from the turbine at 0.8 MPa for the closed feedwater heater and at 0.3 MPa for the open feedwater heater. The feedwater is heated to the condensation temperature of the extracted steam in the closed feedwater heater. The extracted steam leaves the closed feedwater heater as a saturated liquid, which is subsequently throttled to the open feedwater heater. The extracted steam also leaves the open feedwater heater as a saturated liquid. Given h2=192.1 kJ/kg, hs=727.83 kJ/kg, h1=2100 kJ/kg, determine (a) m9/mg = y =? (b) m10/mg = z =? (c) work produced by the turbine per kg of steam entering the turbine, and (d) the equation to calculate exergy destruction for the turbine per kg of steam entering the turbine (no calculation required). 8 Turbine Boiler 9 S/6 + + 11 1-y-z T10 5 37 4 3 10 Closed Оpen fwh fwh P II Condenser .2 6.
