water analogy- a simple calculator

BTW, I know it is 1 degree C * second / watt. But what is the physical realization of that like the farad equivalence being 1 gram of aluminum?

Inertia due to mass. The same as an inductor applied conversely.

Well, yeah. But isn't 1 gram of aluminum an inertia?

John

There isn't one. The heat equation is first order with respect to time, and all the coefficients are real-valued, so there's no opportunity for oscillatory solutions. (The Schrodinger equation is also first order in time, but it has a factor of i in it, so all the nontrivial solutions are oscillatory. Second order equations can display both sorts of behaviour.)

I'd have to check the numbers, but I assume that at room temperature the heat capacity of 1 gram of aluminum is about 1 joule per degree K.

Thanks, Dr. Phil. I guess that's why I could not mentally picture such a thing.

Cheers, John
