Answer : 



Specific gravity of milk = 1.035 



Total solids. \-l2X 2= 11.15 per cent. 



Solids not fat ~ + .2 X 2 = 9.15 per cent. 



Specific gravity of milk solids 

 11.15 



11.15 100 X 1.035 ICO 1.446 



1.035 



llxample of milk from which cream was removed and to which 

 r was added. Quevenne lactometer reading at 60 degrees F. 

 32, fat 2 per cent. 



Specific gravity of milk = 1.032 



Total solids ^~-+ 1.2 X 2 =10.4 per cent. 



3? 

 Solids not fat ^ 1- .2 X 2 = 8.4 per cent. 



Specific gravity of milk solids 

 10.4 



10.4 100 X 1.032 100 = 1.425 per cent. 

 1.032
