In the extrusion of cold chocolate from a tube, work is done on the chocolate by the pressure applied by a ram forcing the chocolate through the tube. The work per unit mass of extruded chocolate is equal to p/r, where p is the difference between the applied pressure and the pressure where the chocolate emerges from the tube, and r is the density of the chocolate. Rather than increasing the temperature of the chocolate, this work melts cocoa fats in the chocolate.These fats have a heat of fusion of 150 kJ/kg.Assume that all of the work goes into that melting and that these fats make up 30% of the chocolate’s mass.What percentage of the fats melt during the extrusion if p = 5.5 MPa and r = 1200 kg/m3?

When a .22-caliber rifle is fired, the expanding gas from the burning gunpowder creates a pressure behind the bullet. This pressure causes the force that pushes the bullet through the barrel. Suppose the barrel has a length of 0.633 m and an opening whose radius is 2.67 x 10-3 m. A bullet (mass = 2.6 x 10-3 kg) has a speed of 348 m/s after passing through this barrel. Ignore friction and determine the average pressure of the expanding gas.
