Assignment #$5$

For LDPE with the following conditions determine:

Screw Power $($at $T=200C)\frac{J}{s}$

Heat Transfer Coefficient $\frac{W}{m^2}K$

$,$ Melt Temperature $C$

Reminder

Polymer has a melting temperature, so it is crystalline

$F_z=$exp$(\frac{H}{W})-(\frac{H}{W}{)}^3+2\mathrm{.}2(\frac{H}{W}{)}^2-1\mathrm{.}05(\frac{H}{W})$

Pressure flow $\frac{m^3}{s_{?}}$

$Q_d^{}=\frac{-\frac{\frac{m^3}{s}}{*D_b}*H^3(1-\frac{e}{L})*sin\frac{O}{*}cos\frac{O}{*}{10}^{-9}}{2x60}$

$m_p^{}{?}^{\frac{kg}{?}}=3hr3600\mathrm{.}1000.Q_p^{}*{}_m$

$Q_p^{}=\frac{-*D_b*H^3(1-\frac{e}{L})*si{n}^2\frac{O}{*}{10}^{-4}}{12x{}_a*L}$
