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. [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.
