n a single-barrel extrusion system, the operator observes that the extrudate (made of polyethylene, PE) is being processed at a speed of 0.5m/s with a final diameter of 0.5cm. The screw pitch is 1cm, the barrel diameter is 1.5cm, the barrel length is 10cm, the screw channel depth is 0.3cm and the screw is rotating at 10RPM.  a. Find the head pressure on the die given that the polyme

I only need the answer to question 2. I provided the correct answer for question 1 1)An extruder barrel has a diameter of 4.0 in and an L/D ratio of 28. The screw channel depth = 0.25 in, and its pitch is 4.8 in. It rotates at 60 rev/min. The viscosity of the polymer melt is 100 x 10-4 lb-sec/in2. What head pressure at exit is required to obtain a net volume flow rate of 150 in3/min? Assume that you are extruding 1/2 in PVC pipe (schedule 40) using the conditions above. -2193 lb/in2 2) How long would it take to extrude a 30 foot section? Be sure to note in your solution where you got your dimensions for the PVC pipe.
