A BTU is a relatively small amount of energy about equivalent to the heat generated by striking 1 stick match. Flow rate to tube size is important to make sure that the Reynolds number is high enough to create turbulent flow and prevent a boundary layer from forming, effectively insulating the tube surface from the bulk temperature of the fluid. When the first coil returns to its original position, it possesses the same amount of energy as it had before it was displaced. Then, for a conical coil (smaller radius at the bottom than at the top) the metallic sample will move upward due to this levitation force, until the force of gravity balances the force of levitation.
