An extrusion operation produces continuous tubing with outside diameter = 5 cm and inside diameter = 4.25 cm. The extruder barrel has a diameter = 10 cm and length = 3 m. The screw rotates at 50 rev/min; it has a channel depth = 0.63 cm and flight angle = 16°. The head pressure has a value of 2.5 MPa and the viscosity of the polymer melt is 55 Pa-s. Under these conditions, what is the production rate in length of tube/min, assuming the extrudate is pulled at a rate that eliminates the effect of die swell (i.e., the tubing has the same OD and ID as the die profile)?
