X 3600 Pm = 0.58 X 140 = 81.2 lb. per sq. in. absolute. Locate the initial condition of the steam at theintersection of the 140 lb. pressure Hne and the saturation curve. The heat content as read on the left-hand vertical scale is: u = 1194. From the intersection on the saturation curve, above… … Fig. 7. Wheel Disc. until the intersection with a diagonal pressure line corresponding to P2 = 15.7 is reached. The qualityX2 is found to be 0.878 and the heat content 1035.
