A turbine operating under steady flow conditions receives steam at the following state: Pressure: 13.8 bar, Specific Volume: 0.143 m³/kg, Internal Energy: 2590 kJ/kg, Velocity: 30 m/s. The state of the steam leaving the turbine is: Pressure: 0.35 bar, Specific Volume: 4.37 m /kg, Internal Energy: 2360 kJ/kg and Velocity: 90.195 m/s. Heat is lost to the surrounding at the rate of 0.25 kJ/s. If the rate of steam flow is 0.38 kg/s, the specific work developed by the turbine =

A turbine operating under steady flow
conditions receives steam at the following
state: Pressure: 13.8 bar, Specific Volume:
0.143 m3/kg, Internal Energy: 2590 kJ/kg,
Velocity: 30 m/s. The state of the steam
leaving the turbine is:
Pressure: 0.35 bar, Specific Volume: 4.37
m3/kg, Internal Energy: 2360 kJ/kg and
Velocity: 90.195 m/s. Heat is lost to the
surrounding at the rate of 0.25 kJ/s. If the
rate of steam flow is 0.38 kg/s, the specific
work developed by the turbine =
Select one:
a. 201.24 kJ/kg
b. 270.115 kJ /kg
c. 269.86 kJ/kg
d. 3343.38 kJ/kg
