WebbThe vapor quality at the turbine exit decreases for optimum expansion from x 8 = 0.94 when T b = 200 °C to x 8 = 0.83 and boiling temperature is 280 °C. Figure 5.10 . Variation … WebbThis corresponds to a pressure of P = 1.32 M P a from the steam tables. To determine the water/steam temperature at the pinch point (Ts1), we can use the fact that the steam leaves the turbine at 90% quality. From the steam tables, we can find that the saturation temperature at 1.32 MPa is T 1.32 M p a = 191.4 o C .
