G Using the data given below, calculate the drop in the temperature of molten aluminum as it flows in a 15 cm long round channel of 2 cm diameter in a water-cooled die. Assume that Al enters the channel at 800 C. The average flow velocity is 4 cm/s. Given: density of Al=2.2 g/cm3, specific heat of Al=0.28 cal/g. K, mold-metal interface heat transfer coefficient=0.01 cal/cm2.s. K, and the die temperature=27 C (assumed constant)
