Page 6 - ... the cylinder of a steam engine that there would be absolutely no transmission of heat either to or from the steam during expansion, a true adiabatic curve or "curve of no transmission" might be obtained. The closer the actual expansion curve of a diagram conforms to such a curve, the higher will be the efficiency of the engine as a machine for converting heat into work. . Fig.
Page 11 - Define a thermal unit, and explain what is meant by the latent heat of steam. Saturated steam is steam in contact with the water from which it is generated. It is at its greatest density corresponding to the temperature and pressure at which it is formed. Its physical condition is such, that at the slightest increase of pressure or decrease of temperature it is ready to yield some portion of liquid. For a given pressure there is one temperature...
