Five grams of 1.5 denier polyester fibre of density 1.39 g/cm3 is packed in a cylinder of 30 mm diameter with perforated ends to make a fibre plug of 20 mm length.

Question 72 (Textile Engineering & Fibre Science)

If 1.2 denier fibre is tested in place of 1.5 denier fibre, the percentage change in the flow rate would be

[Show Answer]

Option A is correct.



Denier 2=1.2

Air flow rate \Alpha  \rho \times dia

f \Alpha  \rho \times D

\frac{f_1}{f_2}=\frac{ \rho_2 \times D_2}{ \rho_1 \times D_1}
