A steam power plant operates between the pressure limit of 3.0 Mpa for the boiler and 75 kPa for the condenser. If the plant operates in an ideal Rankine cycle with superheated vapor enters the turbine at 3 Mpa and 400 oC, determine: a) the moisture content at the inlet of the condenser, b) the net work per unit mass of steam flowing, in kJ/kg, c) the heat transfer to the steam in the boiler in kJ per kg of steam, d) the thermal efficiency, e) the heat transfer to cooling water passing through the condenser, in kJ per kg of steam flowing. hl (kJ/kg) Format : 959.77 v1 (m3/kg) Format : 0.003033 h2 (kJ/kg) Format: 353.2222 h3 (kJ/kg) Format : 5723.7 s3 (m3/kg) Format : 3.9392 x4 Format: 0.864 h4 (kJ/kg) Format: 6347.95 W (kJ/kg) Format: 396.92 Qin (kJ/kg) Format 3887.64 Efficiency (%) Format: 68.25 A steam power plant operates between the pressure limit of 3.0 Mpa for the boiler and 75 kPa for the condenser.
