A plate of aluminum alloy with dimensions 6mmx300mmx300mm is soultionized at 810 K and then quenched into water at 365 K. Over the temperature range 810-535 K, the heat transfer coefficient for quenching may be assumed constant at 510 W.m.K'. (a) Calculate the cooling rate during quenching at that instant when the plate is at 590 K. (b) Repeat when the plate is at 420 K. (c) Determine the time it takes the plate to cool to 390 K. The properties of the aluminum are: k = 78 W m'K', C,=100 J.kg".K',p=2880 kg.m
