I understand you're looking for a long write-up related to the solution manual for "Ciencia e Ingeniería de los Materiales" (The Science and Engineering of Materials) by Donald R. Askeland, 3rd edition (Spanish version). [ 0,71 = \frac{0,0008}{2 \times 3

[ \frac{C_s - C_x}{C_s - C_0} = \text{erf}\left( \frac{x}{2\sqrt{Dt}} \right) ]

Donde: ( C_s = 1,2% ) C, ( C_0 = 0,10% ) C, ( C_x = 0,45% ) C, ( x = 0,0008 , \text{m} ), ( D = 1.4\times10^{-11} , \text{m}^2/\text{s} ). 71 = \frac{0

[ 0,71 = \frac{0,0008}{2\sqrt{(1.4\times10^{-11}) t}} ]

( t \approx 6,3 , \text{horas} ).

[ 5.313\times10^{-6} \sqrt{t} = 0,0008 ]
