Mass flow rate ( dot m)=3.91kg/s Inlet conditions: Pressure (P1)=15MPa Temperature (T1)=450C Outlet conditions: Pressure (P2)=15kPa Quality (x2)=0.87 (or 87% ) Inlet enthalpy (h1) =3447.5kJ/kg Outlet enthalpy (h2)=191.8kJ/kg Inlet entropy (s1)=6.727kJ/(kgK) Outlet entropy (s2)=7.425kJ/(kgK) Mass balance: 3.91kg/s= Mass flow rate of steam leaving turbine Energy balance: 3447.5kJ/kg=191.8kJ/kg+ Work done by turbine Work done by turbine =3255.7kJ/kg Entropy balance: 6.727kJ/(kgK)=7.425kJ/(kgK)+ Entropy generated by the turbine Entropy generated by the turbine =0.698kJ/(kg K) Make the T-S and P-V graphs and explain with the paragraph
