Problem: In a die-casting operation, 0.1 kg charges of molten zinc alloy at 410 degrees C are injected at a rate of 120 charges per hour. The liquid metal has a specific heat of 480 J/kg^-1/K^-1 and a freezing temperature of 400 degrees C. The latent heat of solidificatino of the alloy is 110,000 J/kg^-1. The casting is ejected from the die as soon as it is solid. The insulated die is water cooled at a rate C (Td-T0), where Td is the dye temperature, T0 = 20 degrees C and C has a value of 5 J/s^-1/K^-1. Estimate the average die temperature after a long period of steady operation.
