Consider a single screw melt extruder with the following dimensions: D = 6.0 cm, L = 60.0 cm, H = 0.6 cm, W = 6.0 cm & helix angle of 17.4°. The capacity at open discharge is 10 kg/hour and the viscosity of the polymer melt is 500 Ns/m?. a. Determine the pressure when Q = 5 kg/hr. b. Determine the pressure when a round die of diameter 3.00 cm and length 10.0 cm is attached to the extruder.

Alplas Plastics uses an extruder in which the barrel diameter = 0.4 m and length = 6.0 m. The extruder screw rotates at 65 rev/min; it has channel depth = 0.02 m and flight angle = 16°. The plastic melt has a shear viscosity = 85 Pa-s. Determine: (a) Qmax and pmax; (b) the shape factor Ks for a circular die opening in which Dd = 0.009 m and Ld = 0.03 m; and (c) the values of Q and p at the operating point

What will be the surface roughness x of the product due to the compressibility of the oil in the cylinder of the rectilinear hydraulic motor (PCH) of the copier if the pressing force fluctuates due to the unequal hardness of the material in the range Fmin = 720 N to Fmax = 865 N? The diameter of the PČH cylinder is d = 25 mm, the volume in the cylinder and the supply line is V0 = 55 cm3, the compressibility coefficient of the oil Bp = 4.58*10-10 Pa-1.
