Power output of lava.

How much energy would something with a surface area of ~125.2 m^2 absorb from being fully immersed in lava per second second?
I ask cause I need it for some low end calcs I'm trying to do.

I dont have a clue, but lava comes in many forms. The lava in Hawaii is thin and ropey, the lava here on the West coast is thick and seldom runs freely.
Id think there a different amount of energy in each type. But then you know what they say opinions are like.

Yes, pahoehoe is much hotter than aa.

Nobody believes me when I use aa as a word in scrabble. They always have to look it up.
I always say its called aa cause thats what you say when you step on it.

That depends on the fluidity of the lava as well as the initial temperature and thermophysical properties of the immersed object. Besides, the power curve would not be linear, so you would not get a fixed number in any case. It will start higher and then decrease (perhaps very rapidly, depending on the variables above) until it achieves thermal equilibrium, at which point the net heat flux will be zero. There are many metallic and ceramic objects that you could immerse in lava indefinitely.

Then I suspect that answer wasn't the one you wanted. Sorry.
