Book excerpt: Excerpt from The Heat Engine Problem It is now a good many years since the first proposition was made for obtaining work by the heat-transforming action of a perfect gas and though each process as it appeared has been more or less completely worked out by those interested in it to show the possibilities of the system and compare it with others yet no investigation of all systems with their mutual relations has ever been made by a general method. This is desirable because no comparisons can be justly drawn otherwise and it is, unfortunately, true that invariably in the past the best conditions of one system have been selected for comparison with some other system working under indifferent conditions. This may not have been done intentionally, in fact it appears that in many cases the comparison seemed perfectly just to the author but the results are almost valueless as bases of generalization for the purpose of reaching clear notions of comparative value. A commonly used mode of comparison considers different cycles working through the same temperature range whereas equal quantities of heat for each case will result in different temperature ranges and it is pretty clear that comparisons should be made on the basis of some initial conditions one of which is the heat supplied. A perfect gas will transform heat into work and considering the gas alone without reference to any engine the fraction of the heat that is transformed is dependent on the relation both in sequence and extent of the operations of heating, cooling, expansion and contraction - in short is dependent on the cycle first and the extent of each cyclic phase secondly. It is first required to find out just how much heat energy will be transformed by each cycle and if other things are equal one should be the best for application to engines. But in this comparison we should consider not only which cycle transforms the largest amount of the heat energy supplied to it into work but also through just what range of pressures, volumes and temperatures these cycles must operate to produce the work.
