Question 36 (Textile Engineering & Fibre Science)
If the distance between two adjacent fibres of circular cross-section in a hexagonally packed yarn is equal to the radius of the fibre, then the packing density of yarn, accurate to three decimal places, is __0.380 to 0.420__.
Given in the question:
In hexagonally packing
If, distance between two adjacent fibres of circular cross-section= a
And dia of fibres=d
i.e., Radius of fibres=d/2
Packing density of yarn(P.C)=0.385 (Answer)
