168 FLUIDITY AND TEMPERATURE OF LIQUIDS. CREIGHTON 



By multiplying a particular temperature Tb by the correspond- 

 ing temperature ratio (read off from the curve), the absolute tem- 

 perature Ta is obtained at which the fluidity of liquid A is 

 equal to that of liquid B at the absolute temperature Tb. In 

 this way the fluidity of liquid A over the whole range of known 

 fluidities of liquid B may be calculated.
