The following data refers to a cone winding process:
– Package diameter = 20 cm
– Package height = 25 cm
– Drum diameter = 8 cm
– Scroll of the drum = 2.5
– Winding speed = 1000 m/min
Question 61 (Textile Engineering & Fibre Science)
The rpm of the drum is approximately
(A) | 3,000 |
(B) | 3,400 |
(C) | 3,700 |
(D) | 4,000 |
[Show Answer]
Option D is correct.
Given-
Package diameter = 20 cm
– Package height = 25 cm
– Drum diameter = 8 cm
– Scroll of the drum = 2.5
– Winding speed = 1000 m/min
By formula-
Winding speed=
Where, D is the dia of drum and N is the rpm of the drum.
1000=
The rpm of the drum(N)=4000 RPM (Ans)
