QUESTION 3
Steam at 2MPa, 600°C enters an adiabatic turbine and undergoes irreversible expansion to a saturated vapor condition at 0.01 MPa. The steam flowrate is 20 kg/min.
(a) Write the general entropy balance and explain how you come up with the final entropy balance for the turbine.
(b) What is the entropy generation (kJ/K.min) for this process and is this process possible.
(c) What are the outlet temperature (°C) and enthalpy (kJ/kg)?
(d) Calculate the turbine work in kW.
(e) Explain whether the work produced in part (d) is an actual or ideal work.
(f) Draw this process on a T-s diagram.
