 It has been shown that: 1. The loss of heat from wires by free convection takes place exactly as if there were a film of stationary gas around the wire, through which the heat is carried entirely by conduction. 2. The thickness of the film is independent...  Physical Review - Página 4191912Vista completa - Acerca de este libro
