16-10C When the wall thickness of the tube is small and the thermal conductivity of the tube material is high, which is usually the case, the thermal resistance of the tube is negligible. 16-11C The heat transfer surface areas are Ai =πD1L and Ao =πD2L. When the thickness of inner tube is small, it is reasonable to assume Ai ≅Ao ≅As.
Aug 17, 2018 Detune the acetylene torch and coat the area to be bent with soot. Turn back the O2 and set your rosebud tip to an ordinary flame. Heat the part uniformly until the black soot goes away. This should anneal the 6061-T6 (or other “T”) into a T-0 material. This makes the aluminum about as bendable as it can get.
