I 1 MI'I KATl Kl ! \TROPY TABLE. 



THIS table gives the properties of moist and of superheated steam at 

 each degree of temperature Fahrenheit, and for each hundredth of a unit 



At tlu- left hand of each page are given tin- trmj*- natures and the corre- 

 sponding pressures of saturated steam; the lines across the tables are, 

 constant pressure lines, and for moist steam are also ***fffint 

 tem|>erature lines. 



The table is divided by a broken line which corresponds roughly to the 

 saturation line; properties to the left of that line are for moist 

 to tlie right are for -u|>crheatcd steam. 



The triple i olumns are headed with the entropy, and are 

 entropy lines; they can be used for Diving problems concerning ad ia baric 

 operations in a closed Cylinder, and similar problems. 



.my point in the table, determined by the entropy and the pressure 

 (or t! ponding temperature of saturated steam), there are given 



three pr. 



(i) The quality, whirh for moist steam is the proportion of a pound 

 that is steam, and for superheated steam is the number of degrees of super- 

 heati 



(a) The heat contents, or the number of thermal units required to change 

 a pound of water at freezing into steam at the given pressure and with the 

 given quality. 



(3) The specific volume in cubic feet per pound. 



For examples, solved by aid of the table, see page 30.
