Question #42794
Kiwis love a summer barbecue, but there is nothing worse than having a hot drink on a hot day. Luckily, you happen to know a bit about thermodynamics and heat transfer, so have decided to design yourself a chilly-bin. You have six 355mL cans of drink at 8°C that you don’t want to get above 10°C for the three hours before the barbecue (the ambient temperature is 28°C), but you don’t have any ice. The air over the outside of your chilly bin can be assumed to have a heat transfer coefficient of 5 W/m2 K. Show a sketch, your calculations (and any assumptions you have made) and provide a 250 word discussion justifying your design.
