Unformatted text preview: 8-4&5EquationsSet 23: Problem 8.4 and 8.5Water is the working fluid in an ideal Rankine cycle. Steam enters the turbine at 8 MPa and 480◦C. The net power output of thecycle is 100 MW.8-4 Plot the following quantifies versus condenser pressure ranging from 6 kPa to 0.1 MPa for a turbine inlet pressure of 8MPa8-5 Plot the following quantifies versus turbine inlet pressure ranging from 4 MPa to 24 MPa for a condenser pressure of 8 kPaa) the mass flow rate of steam in kg/hrb) the thermal efficiencyc) the mass flow rate of cooling water to the condenser if the water enters at 15 C and exits at 35 CNumber states indicated in theEESdiagramwindowW$ =‘Water’(1)T1= 480 [C]turbine inlet temperature(2)$Ifnot ParametricTableP1= 8000 [kPa]conditions for problem 8-2(3)P2= 8 [kPa](4)$endifPower= 100 [MW]·1000kWMW(5)Turbines1= s(W$,T=T1,P=P1)(6)h1= h(W$,T=T1,P=P1)(7)s1=s2(8)h2= h(W$,P=P2,s=s2)(9)T2= T(W$,P=P2,s=s2)(10)x2= x(W$,P=P2,s=s2)(11)Wt=h1-h2(12)Condenserx3= 0(13)P3=P2(14)h3= h(W$,P=P3,x=...
