e kinetic energy term is negligiblein comparison with W for each separate stage, it is so for the wholeturbine, and if e is the efficiency in the usual sense we have (Fig. 2) AD=ACWhen 6 refers to a single stage it is called the * stage efficiency, *for, as we shall see in section 9, a distinctive… … *R ■> Fig. 4 and that the expansion line can therefore not in reality be asmooth curve like AB in Fig. 2. Let us consider the simple caseof a three-stage impulse turbine working with wet steam betweenthe pressures p^ and p^, the intermediate pressures at entrance tothe second and third stage…
