Given in the question–
Cotton processing=600 kg/h
Waste generated=2%
Lint:Trash=60:40
The lint accumulation in 8 hrs=?
Calculation–
Waste(kg/h)=Cotton processing x waste%
Waste(kg/h)=600 x 2/100
Waste(kg/h)=12
Lint accumulation(kg/h)=Waste in kg/h x lint %
Lint accumulation(kg/h)=12 x 60/100
Lint accumulation(kg/h)=720/100
Lint accumulation(kg/h)=7.20
Lint accumulation(kg/8h)=7.20 x 8
Lint accumulation(kg/h)=56.6 (Answer)
