The presentation had to be very much abbreviated, and Often the development was only indicated, still to the closely interested reader the proof also will probably be everywhere evident.
In order to facilitate the study the book 13 divided into three parts. In the first, the principles peculiar to turbine are discussed. In the second are found investigations requiring more advanced mathematical preparation. The third part is greatly amplified and gives a short résumé of the mechanics of heat; for there is no doubt but that a thorough understanding of the energy transforma tion in a steam turbine can be gained only by having thermodynamic foundation. The abstract theory of unresisted ?ow must be given up when we deal with actual problems; and in order to accomplish this, no means will suffice but a thorough understanding of entropy, which, with the help of our entropy diagram, will permit of the easy solution of all heat problems. To encourage the practical engineer, to freshen up on the somewhat forgotten principles of thermo dynamics, the fundamental laws Of this science have been brie?y derived for heat motors. To the thoughtful student, the discus sions in these chapters may be recommended as an introduction. I have made use of the opportunity to present the second funda mental law of thermodynamics from one of the modern points of view, starting from perpetual motion of the second type. The derivation given by Planck, which still shows some obscurity on close inspection, has been replaced, I hope, by a more satisfactory presentation. The more this second fundamental law has been attacked, the stronger has it proved itself, and for this reason we caution inventors not to attempt any violation of this fundamental law of our science.
