ighpressure is greater than that at low pres-sure. Upon reaching the chamber, C,the steam therefore may contain anamount of heat in excess of that necessaryfor saturation, and this excess goes toevaporate the moisture carried in withthe steam and to superheat both. In thiscondition, the heat… … Fig. 70.Throttling Calorimeter. the H2O is hi+xLi. eter chamber, it is Ji2+L2+CP(T2- from which, h1+xL1 = h2+L2+CP(T2-t2).h2+L2 + Cp(T2-t2)-h1 x = u The values of h and L and t2 are found from the steam tables,by reference to the pressures indicated by the pressure gage Pand the manometer M, Fig.…
