TABLES 254-260.— THERMAL PROPERTIES OF GASES 



The properties given in Tables 254 and 256-258 are taken from a series of 

 tables of thermal properties of gases being compiled at the National Bureau of 

 Standards at the suggestion of and with the cooperation of the National Ad- 

 visory Committee for Aeronautics. The functions in these tables have been ex- 

 pressed in dimensionless form in order that they may be converted readily to 

 any system of units. Conversion factors are listed for the most often used 

 units. For more extensive data on various gases reference should be made to 

 these tables. 82
