Comparing the calculated and observed results, we have; 



For the first phase 



For the second phase 



dii = 46.22 e ^ for the second phase in cm. 



Comparing the calculated and observed results, we have:

3°. Applying the equation vs=c„e i for each phase, we find: 



_ 6L303 

 vs =\A42e t for the first phase in cub. m, 



103.0746 

 %„ = 3.014e i for the second phase in cub. m.
