Question 34 (Textile Engineering & Fibre Science)
In a sizing machine, 100 m length of warp sheet was processed. The warp was stretched by 3%, 2% and 1% at unwinding zone, wet zone and drying zone respectively. The length of warp sheet on weaver’s beam will be
| (A) | 106.00 m |
| (B) | 106.11 m |
| (C) | 103.11 m |
| (D) | 100.06 m |
[Show Answer]
Given in the question-
Warp sheet length=100 meter
Warp stretch % at unwiding zone= 3%
Warp stretch % at wet zone= 2%
Warp stretch % at drying zone= 1%
Length of warp sheet on weaver’s beam=?
Now,
Length of warp sheet on weaver’s beam=Length Warp sheet x (1+Warp stretch % at unwiding zone) x (1+Warp stretch % at wet zone) x (1+Warp stretch % at drying zone)
Length of warp sheet on weaver’s beam=100 x (1+3%) x (1+2%) x (1+1%)
Length of warp sheet on weaver’s beam=100 x (1+3/100) x (1+2/100) x (1+1/100)
Length of warp sheet on weaver’s beam=100 x (1+0.03) x (1+0.02) x (1+0.01)
Length of warp sheet on weaver’s beam=100 x (1.03) x (1.02) x (1.01)
Length of warp sheet on weaver’s beam=106.11 meter (Ans)
