http://web.mit.edu/10.213/www/exams/exam2sol.pdf 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 .
