Page 14 - It is impossible for a self-acting machine, unaided by any external agency, to convey heat from one body to another at a higher temperature.
Page 27 - Avogadro's celebrated enunciation of the theorem that equal volumes of gases at the same pressure and temperature contain equal numbers of molecules is sufficient authority for the principle of equal molal volumes.
Page 143 - D = density of steam, weight per cubic foot, at initial pressure pc, pt = initial pressure; p, — final pressure; L = length of pipe, in feet; d = diameter of pipe, in inches. The difference pt — p, is equal to the drop in pressure in the pipe.
Page 14 - No change in a system of bodies that can take place of itself can increase the available energy of the system.
Page 72 - TRANSMISSION OF HEAT Preliminary Statements. There are three methods by which heat may be propagated or conveyed from one place to another. 1. By Conduction. In this method heat passes from one body to another or from one part of a body to another by contact.
