A steam power plant operates on a Rankine cycle. Steam enters the turbine at 4 MPa, 350°C and exits at a pressure of 15 kPa. Then it enters the condenser and exits as saturated water and the boiler feed pump delivers the water back to the boiler. The thermodynamic properties of the working fluid are given in the tables below. Consider an adiabatic efficiency of the turbine to be 87 percent. Draw and label the T-s diagram and solve for the following: 4.1 Turbine work. 4.2 Work net output 4.3 Heat supplied to the boiler State @4MPa & 350°C h (kJ/kg) 3092.5 s (kJ/kg-K) v (m³/kg) V 6.5821 0.06645 hg Sr Sg Vr Vg @15 kPa 225.94 2599.1 0.7549 8.0085 0.001014 10.02
