We ...pass on to the calculation of the specific volume of saturated water-vapor. 2. Calculation of the Specific Volume of Saturated Water-vapor. The first question to consider is, whether in its saturated state water-vapor follows the law of Mariotte-Gay-Lussac, and if it does not, to what extent and in what way deviations occur. Making use of the fundamental relation (IIP), we find, after replacing (s — a) for u. r = T{s - a- ) dp " dt J REVERSIBLE CYCLES IN OASES AND VAPORS. 79 or 273>- _ %np(s - a) ^,ldp J(273 + p dt If the Mariotte-Gay-Lussac law were applicable to satu- rated water - vapor^ then from ^ = const, we should have ps X 373 , ^273+T) = °°'^^*' Since s differs but little from (s — a), we should have p{s - o-)273 Comparing this to the equation just obtained from the funda- mental relation (IIP), we see that if the Mariotte-Gay-Lussac law were applicable to saturated water-vapor we should have %nr _ p{s - o-) 273 _ pdt Having calculated - ;3t hy the method described above, and J- from the formula r = 607 — .708^, and substituted their 80 THERMODTNAMIGS OF values in the last equation, Clausius obtained the following table : J.U/U -•^/j/'vo "^273 + r
