Excerpt from Handbook of Thermodynamic Tables and Diagrams: A Selection of Tables and Diagrams From Engineering Thermodynamics
Time is an important item in all engineering work and none the less so in computations, so that convenient tables and diagrams are most essential to ... the solution of such problems. In some cases graphic methods are the only means of solution; in others the problems may be solved directly without the use of formulas, and in still others certain steps may be Shortened. In many engineering calculations no one is justified in using a complicated mathematical formula; if too much time be required to make the calculation in commercial work it will not be made, therefore indirect and often approximate methods are substituted. In such cases the nearest tabular or chart value must be used, and generally the result will be as accurate as the work requires.
In the following tables and charts the accompanying title usually, indi cates the character of each table or diagram and little explanation is necessary. The tables for dry saturated steam, and properties of superheated steam are those of Marks and Davis. From the investigation made by Marks and Davis it is believed that the properties of saturated steam given in the tables are correct to within one-tenth of 1 per cent. For pressures within the range of ordinary engineering practice.
