টেক্সটাইলে ইঞ্জিনিয়ার হিসাবে কাজ করতে হলে আপনাকে প্রতিনিয়ত নানা রকম হিসাব করতে হবে। আর সেই হিসাব করতে আপনার লাগবে গণিতের নানা রকম সুত্র ও পরিমাপের একক। এই আর্টিকেলে সেই সব সম্পর্কেই বিস্তারিত লেখা রয়েছে।
✏️ ওজন পরিমাপের ব্যবহৃত ইউনিট সমূহ: (Conversion of Weight Units In Yarn Manufacturing)
▶️1kg=2.2046 lbs
▶️1kg=1000 grams
▶️1gm=15.432 grains
▶️1lbs=453.6 grams
▶️1lbs=16 oz
▶️1lbs=7000 grains
▶️1grain=0.0029 oz
▶️1oz=437.50 grains
▶️1penny=24 grains
▶️1ton=2204.6 lbs
▶️1bundle=10 lbs
▶️1bag=100 lbs
▶️1mund=40kg
▶️1mund=88.18 lbs
✏️দৈর্ঘ্য পরিমাপের ইউনিট সমূহ: (Conversion of Length Units)
Conversion |
▶️1m=1.0936 yards
▶️1m=39.37 inches
▶️1m=100 cm
▶️1m=1000 mm
▶️1cm=10 mm
▶️1yard=36 inches
▶️1yard=0.9144 meter
▶️1yard=91.44 cm
▶️1ft=304.8 mm
▶️1ft=30.48 cm
▶️1hank=840 yards
✏️ পরিবেশ ও আর্দ্রতা পরিমাপের জন্য: (Moisture Relation for Textile Materials)
Moisture Relation |
▶️M.R=W/D × 100
▶️M.C=W/W+D × 100
▶️M=R/(1+R/100)
▶️C.C.W=D × (100+R/100)
▶️D=C.C.W × (100/100+R%)
▶️C.C.W=D+R%
▶️C.C.W=D+(D×R/100)
▶️Dm=√(D1+D2+D3)^2
▶️Volume of air=area(feet sq) × liner speed(ft/min)
✏️ব্লো রুমের জন্য: (Blow Room Section)
Blow Room |
▶️Cleaning Efficiency =trash removed/total trash fed × 100
▶️Efficiency=tr/tf × 100
=tf-tr/tf × 100
▶️Waste=trash+lint
▶️Waste Extracted=weight fed×waste%
▶️Weight Extracted=weight fed–weight delivered
▶️Weight Delivered = weight fed–waste extracted
▶️Weight Delivered = weight fed×(100–w/100)
▶️Weight Fed=weight delivered ×(100/100–w)
▶️Lap length =lap length constant×lap length constant wheel
▶️Beats/min=rpm of beater×number of strikers
▶️Beats/inch=beats per minute/feeding rate(inches/min)
▶️Beats Constant= beats/inch × rpm of paddle roller
▶️Beats Constant=beat per minute/feeding rate
▶️Efficiency=actual production/calculated production × 100
▶️Actual Production=calculated production×efficiency
▶️Actual Production=weight of lap(lbs)×number of lap/hr
▶️M.D=s.s of shell roller/s.s of paddle roller
▶️Production of B/R(lbs/hr)=production constant ×N(shell roller rpm)×W(oz/yd)
