78. A steam turbine receives 5,000 kg/hr of steam at 5 MPa and 400°C and velocity of 30 m/s. It

leaves the turbine at 0.006 MPa and 85% quality and velocity of 15 m/s. Radiation loss is 10,000

kJ/hr. Find the kW developed.

@5 MPa and 400°C: h1 = 3195.7 kJ/kg s1 = 6.6459 kJ/kg-K

@ 0.006 Mpa: hf = 151.53 kJ/kg hfg = 2415.9 kJ/kg
