Book Description
Excerpt from Vapor Pressure of Ammonia The accuracy of any vapor-pressure measurements is determined, in general, by four factors; namely, (a) purity of the material, (6) certainty, pf feqmlibrium; conditions, (c) precision of the pressure-measuring instrument, and temperature measurement and control.

Excerpt from Specific Heat of Superheated Ammonia Vapor Other quantities which enter into the determinations of the specific heat as small corrections are heat leakage and the effect of pressure drop. The evaluation of these quantities is discussed in later sections of this paper. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from The Properties of Saturated and Superheated Ammonia Vapor The first attempt to establish the fundamental equations for the vapor (ff ammonia and to compute tables of its properties was made by Ledoux.6 These equations and resulting tables, resting as they do upon unsound hypotheses and meager experimental data, are, in the light of later investigations, quite inaccurate. The next theoretical investigation of the subject was undertaken by Zeuner,7 who computed new constants for ammonia, in the equation of state of the form already applied by him to steam, and used by Ledoux for ammonia. He also constructed empirical formulas for the inner and outer latent heat, and the specific heat'of the liquid, and by use of these formulas computed tables which. Appeared in the earlier editions of his thermodynamics.8 In the later editions9 the values thus calculated have still been used for temperatures below 32° F., but results of later experimental deter minations have been used above that temperature. These tables for ammonia vapor are given in both English and French units. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from Latent Heat of Vaporization of Ammonia The equation as developed above expresses the heat, Qabc, added when the entire amount, am, is evaporated at a constant temperature He and removed at the constant pressure are and con stant temperature 09. In the actual experiments, however, the temperatures of evaporation and superheat do vary somewhat during the process of evaporation and removal. It is therefore n Acessary to generalize equation (1 3) so as to take account of these variations. Obviously, only the terms which depend upon Ge and 08 need be considered with respect to the change which is required in the equation.

Book Description
Excerpt from Specific Volume of Saturated Ammonia Vapor Direct measurements of the Specific volume of ammonia involv ing a determination at various temperatures of the mass of satu rated vapor contained in a known volume were undertaken at the 'b ureau of Standards several years ago. The precision of these measurements below 0° C. Proved to be less than was hoped, and an optical method, in which the specific volume of the vapor was calculated from its measured index of refraction, Was also employed. This work was interrupted during the War and the subsequent death of one of the authors and the absence of the other authors from the bureau has delayed the publication of the results.
