Q(5): A piece of aluminum (p=2705 kg/m, k=216 W/m.°C, Cp=896 J/kg.°C) having a mass of 4.78 kg and initially at a temperature of 290°C is suddenly immersed in a fluid at 15 C. The convection heat transfer coefficient is 54 W/m".°C. Taking the aluminum as a sphere having the same mass at that given, estimate the time required to cool the aluminum to 90°C. Find also the total neat transferred during this period.
