In powder processing, a cylinder with a diameter of 2 inches and a height of 10 inches is to be made from fine copper powders. A single-action press is used for compaction. If the average density of the green product is 7 g/cm3 at the bottom half of the cylinder, estimate the compaction pressure at the punch surface. Assume no friction between the powders. The coefficient of friction between particles and containers is 0.2.

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.
