Solution<br />
Power Zc in the screw channel:<br />
DFLT = 59.8 mm from Equation 5.44<br />
Shear rate in the screw channel fc:<br />
yc = 83.8 s" 1 from Equation 5.36<br />
aT = 0.374 from Equation 1.34<br />
Viscosity of the melt in the screw channel r\c<br />
ric = 1406.34 Pa <strong>•</strong> s from Equation 1.36<br />
Channel width W:<br />
W= 51.46 mm from Equation 5.45<br />
Number of flights v:<br />
V= 1<br />
Length of the melt zone AL:<br />
Faktor Fx:<br />
AL = 600 mm<br />
TJ O<br />
Fx = 1 for — = = 0.058 from Equation 5.39<br />
W 51.46<br />
Helix angle (fr.<br />
(/) = 17.66°; sin0 = 0.303 from Equation 5.28<br />
Power in the screw channel Zc from Equation 5.41:<br />
Power in the flight clearance ZFLT:<br />
Flight width wFLT (Figure 5.22):<br />
WFLT ~ e cos 0=6' cos 17.66° = 5.7 mm<br />
Shear rate in the flight clearance ^FLT:
