Question

Describe the energy inputs and outputs for the campfire. Use the law of conservation of energy to construct a valid qualitative equation that includes all the input and output energies involved.

Answer 1

I did some fire simulation work recently where a small paper fire (think like half a ream of printer paper) was putting out 4000 watts, or about 5 horsepower. A large roaring campfire is going to be a few multiples of that depending on size, of course.
