In powder processing, a cylinder with a diameter of 2 inches and a height of 10 inches is designed 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 there is no friction between the powders. The coefficient of friction between particles and containers is 0.2
