To warm up some milk for a baby, a mother pours milk into a thin-walled glass whose diameter is 6 cm> the height of glass is 7 cm. She then places the glass into a large pan filled with hot water at 70oC. The milk is stirred constantly, so that its temperature is uniform at all times. If the heat transfer coefficient between the water and glass is 120 W/m2K, determine how long it will take to warm up from 3oC to 38oC. Take all the properties of milk to be the same as those of water.
