In a steam power plant operating on an ideal Rankine cycle, superheated steam enters the turbine at 3 MPa and 350^oC. The condenser pressure is 75 kPa. The thermal efficiency of the cycle is ______ percent.
Given data:
For saturated liquid, at P = 75 kPa, h_f = 384.39 kJ/kg, v_f = 0.001037 m³/kg, s_f = 1.213 kJ/kg-K
At 75 kPa, h_fg = 2278.6 kJ/kg, s_fg = 6.2434 kJ/kg-K
At P = 3 MPa and T = 350^oC (superheated steam), h = 3115.3 kJ/kg, s = 6.7428 kJ/kg-K
