Not illustrated. 1920 Excerpt: ...is practically coincident with that shown in Fig. 23 from 50 to 80 C., and gives very similar results when applied to the calculation of the effects of supersaturation at low pressures, where they are most important. There is some indirect experimental evidence, detailed in Chapter XVI, tending to show that the practical SS limit in turbines may be as high as the line of constant wetness QQ in Fig. 23. If this were the case, it would afford a very simple and practical method of calculation, but the actual position of the line remains uncertain at high pressures, though there is every reason to believe that it cannot be lower than the line SS representing the constant ratio 8, which may be safely assumed as representing the maximum limit of loss due to supersaturation. For this purpose we may accept the Wilson ratio provisionally, though it must be admitted that further experiments are desirable. 107. Reduction of Efficiency by Supersaturation. In the case previously considered, it was assumed, in order to simplify the calculation, that the rapidly expanding steam, on reaching the supersaturation limit, was instantaneously transformed into wet saturated steam in the equilibrium state, and remained in this state for the remainder of the expansion. This method gives a lower limit for the loss due to initial supersaturation. It is obvious, however, that some degree of supersaturation must persist throughout the whole of the expansion, since the transformation cannot be instantaneous. It is, therefore, desirable to make an estimate of the corresponding upper limit of loss, obtained by assuming the supersaturation line SS. For this purpose the supersaturation limit may be defined as the limit of the state of dry supersaturated steam in rapid expansion which is re...
