Problem 6.2 - Turbine Adiabatic Efficiency

Consider the adiabatic steam turbine shown below.

• a. Carefully plot the turbine process on the h-s diagram and indicate the turbine work done on the plot.
• b. Using steam tables determine the specific work output of the turbine [1015 kJ/kg].
• c. Using steam tables determine the entropy generated by this process. Assume that the surroundings temperatue is at 27°C. [0.01 kJ/kg.K]
• d. Discuss these results and determine if this is a feasible turbine design.

Derive all equations used starting from the basic energy equation and the equation for entropy generated in a flow system.
