Question A$-1(20\%)-$ Product and Application

What is the mass flow rate $(W,$ in $k\frac{g}{h}r)$ of the polymer fed to the spinneret? $(5$ points$)$

What is the diameter $($in $)$ of the single filament, assuming its cross section is round? $(5$ points$)$

How long does it take to make a package with $10kgs$ of fiber? $(5$ points$)$

A rope is made by combining $3000$ denier fiber from $100$ packages $.$ If the rope is used to lift an object, what is the maximum weight of the object the rope can lift before breaking it$?$ The tenacity of fiber is $8gpd.(5$ points$)$

Question A$-2(20\%)-$ Production & Quality

Your company is making a melt$-$spun fiber for certain markets. The current product is $3000$ denier with a density of $1\mathrm{.}08\frac{g}{c}{m}^3.$ It is wound up at $V_2=1000\frac{m}{m}in.$ The fiber is formed by extruding the molten polymer $($melt density $=1\mathrm{.}02\frac{g}{c}{m}^3)$ through spinnerets with dimensions shown below.
