Hey everyone. I know I haven’t updated in forever. I’ve been busy, sorry. Anyway, today I just want to share what happens when you leave coffee in crappy paper cups. The less coffee you have, the faster it gets cold and nasty. It looks something like this:
As you can see, as you have less coffee in the cup, you need to drink it exponentially faster in order to avoid a nasty mouth full of cold coffee. This seems to directly contradict Newton’s Law of Cooling, because that only takes into effect the surface area of cooling, temperature difference between mediums and heat transfer coefficient of the fluids, not thermal mass. Yes, I tried to model the cooling of my coffee in Excel. I have friends, I swear.
So, my chart might be way off. I don’t have the equipment at work to perform a proper experiment, nor do I think my boss would appreciate it. Any mechanical engineers care to weigh in and help me understand how to optimize my coffee consumption? (I should really just get an insulated mug, but where’s the fun in that?)
