Question 55 (Textile Engineering & Fibre Science)
The trash content in cotton fed to a beater is 4%. The waste extracted by the beater is 2%. If the waste contains 60% trash, what is the cleaning efficiency of the beater ?
| (A) | 25% |
| (B) | 30% |
| (C) | 35% |
| (D) | 20% |
[Show Answer]
Given-
Trash in cotton fed to beater=4%
Waste=2%
Waste contains=60% trash
Cleaning efficiency of beater=?
So,
Trash extracted by beater=60% x 2/100
Trash extracted by beater=1.2%
Cleaning efficiency%=(Fed trash%-Extracted trash%) x 100/Fed trash
Cleaning efficiency%=(4-1.2) x 100/4
Cleaning efficiency%=70%
