The steam-turbine expansion line on the Mollier diagram and a short method of finding the reheat factor
A 1911 technical paper issued by the National Bureau of Standards for steam-power engineers, setting out a graphical shortcut for locating the turbine expansion line and reheat factor on the Mollier diagram. The plates are line-drawn thermodynamic charts: labelled axes, ruled sloping construction lines, dashed projections, lettered vertices and Greek angle marks on tinted paper, useful as abstract geometric diagram stock.
