Thermodynamics B/C Build

So let me get this straight: for the building portion of the event, do I just construct a small box made out of heat resistant material (styrofoam, cardboard, etc.) and that's it?

Yup pretty much. And make sure it follows all the construction parameters too. Though, why are you asking this so late in the season? Just curious.

A bunch of the regionals haven't happened yet

The original person who was doing this event quit. So I filled in.

Ah, makes sense. Anyway, good luck and happy building!

Hey! How did you come up with that equation. Right now, our graphs are simply the temperature in relation to the time at specific volumes. How do combine all the data points up for multiple trials to get one equation?

I too, would love to get some insight on this. Right now I just use multiple trails to find the average heat retention of my device (78%) and multiply the source bath temp by that number.

I'm pretty sure the equations people use are just based off of Newton's Law of Cooling. However, I wouldn't really reccomend basing predictions off of an equation because we don't live in an idealized world, and it's overall more accurate to just take enough trials to be able to predict for a given temperature, volume, and time.

Yes, I believe they are based on Newton's Law of Cooling. Also, yep, often times just taking many device tests with varying values will work will enough to produce a good prediction. This is what my team does and it has worked well in the past. However, if you can find a good equation that predicts the device temperature well, then you may have something very good on your hands!

I feel like I asked this question before but does the thickness of the material of the insulating device matter significantly in retaining the heat?

Yes, I recall you asking the question, and yes the thickness of the material matters.

Yes me too. But generally the thinner and more layers you can get the better. More layers you can get the better.

Can you explain why a thinner material is better?

It’s not better because it’s thinner, but because you can get more layers in.
