Question 62 (Textile Engineering & Fibre Science)
A typical textile fibre is a two phase entity consisting of crystalline and amorphous fractions. Theoretically the crystalline fraction could be expressed as mass fraction (Xcm) or as volume fraction (Xcv). If pc, pa and pf are the densities of crystalline fraction, amorphous fraction and the fibre respectively, the Xcv is given by
(A) | (pf-pa) / (pc-pa) |
(B) | (pf-pa) . (pc-pa) |
(C) | pf(pf-pc) / (pc-pa) |
(D) | (pc-pa) / (pf-pa) |
[Show Answer]
Option A is correct.
