Make a sketch, in a temperature-entropy diagram, of the expansion path of an axial turbine stage. Illustrate in the diagram the absolute gas velocities and the stage work output. Label axes and clearly indicate temperatures and pressures, both static and stagnation, at the different locations of the stage. Hint: Stagnation temperature, see expression below. Subscript 0 refers to stagnation properties, c is the absolute velocity, and cp the specific heat at constant pressure.
