Now, put X for the drynessfraction of the steam in the steampipe, so that in each pound of stuffwhich comes through E, thereis X pounds of steam and i - Xpounds of water. Then units ofheat per lb. of stufT= X x L+1 x T,but as no work has been takenout of the steam in entering K, thesteam in K must… … (X X L) + T = (Li + Tj) + -48 (t-TO V -(Li +T,)+ •48(t-T,)-TL THE STEAM HYGROMETER. 47 Perhaps the result is better expressed in words as follows:— To the units of superheat in K add the total heat of the lowpressure steam, and subtract the temperature of the high-pressuresteam. Then divide by the…
