2. A steam power plant operates at a high pressure and temperature of 1 MPa and 300°C and a low pressure of 15 kPa. The actual work output (Wa) of the turbine is found to be at 600 kJ/kg with steam flowing through it. Determine (a) the turbine inlet enthalpy (h3) and outlet quality (x4s), (b) the ideal enthalpy at the exit of the turbine, (c) the ideal work load (W4s), (d) the thermal efficiency (nt) based on an actual turbine work load of 600 kJ/kg, and (e) the exit actual enthalpy (h4a).
