A steam turbine operates at steady state. Steam enters the turbine at 2.0 MPa and 350 °C
with a specific enthalpy of 3137.0 kJ/kg and velocity of 30 m/s. The steam leaves the
turbine at 0.1 MPa with a specific enthalpy of 2675.5 kJ/kg and a velocity of 80 m/s. The
inlet is 5m higher than the exit.
(a) Determine the power developed by the turbine if the turbine is well-insulated and
mass flow rate of steam at inlet is 1.5 kg/s.
(b) When the heat transfer of 200 kW occurs from the turbine to the surroundings,
determine the mass flow rate of steam in order to generate the same power from
