A turbine is fed with a mass rate of 3.2 kg / h of saturated water at a pressure of 120.80 kPa. The steam leaves the turbine at the same mass rate and at a temperature of 100.0ºC. Considering the 0.50 title, the end being 0.30. Determine: a) Initial temperature (ºC); b) Specific initial volume (m³ / kg); c) Final pressure (kPa); d) Final specific volume (m³ / kg); e) Specific variation of enthalpy (kJ / kg)
