Lead is extruded through a horizontal die under a pressure difference of 154.45 MN/m^2. What will the temperature rise of the lead be if there is no cooling while passing through the die? Assume lead to be incompressible and to have a density of 11360 kg/m^3 and a specific heat capacity of 130 J/kg K. Consider the steady-flow energy equation applied to the given extrusion process. Since the die is horizontal then there will be no change in potential energy from inlet to outlet. Hence the potential energy terms can be neglected. The velocity is also low in which case any change in kinetic energy which occurs will be small enough to be sensibly neglected. There is no cooling and also no external work done in which case these terms can also be neglected.
