PRESSURE-ENTROPY TABLE FOR STEAM 



following Ml !' supplements Tables I and 3. 1 1 will be found iwr- 

 ful in the solution of problems that involve adtabatic prnrnsfi. cspcriill) 

 problems concerning the flow of steam through nozzles, and the behavior 

 of steam in turbines. 



Values of the entropy from 1.50 to 1.85 with intervals of o.oi art 

 i at the top of the table. The steam pressure is taken as the other 

 argument, and values of the pressure are given at the left-hand 

 of the page. In the second column are given the com 

 tures of saturated steam. For each entropy value there are three 

 of numbers. In the first column, denoted by x, is found for a given 

 sure the temperature of the superheated steam, or (below the heavy 

 broken line) the quality of the mixture of steam and water; the other 

 columns give respectively the heat content i in B.t.u. and the volume r 

 in cubic feet per pound. The pressure intervals are so selected that 

 values of these properties for intermediate pressures may be easily ob 

 el by interpolation, and the table is so arranged that all data por- 

 ting to a given value of the entropy are found on 

 each other.
