Stainless steel, also known as inox, corrosion-resistant steel (CRES), and rustless steel, is an iron-based alloy containing a minimum level of chromium that is resistant to rusting and corrosion. Stainless steel's resistance to corrosion results from the 10.5%, or more, chromium content which forms a passive film that can protect the material ...
A pipe one inch in diameter and two feet long can transfer 3.7 kW (13,000 BTU/h) at 1,800 °F (980 °C) with only 18 °F (10 °C) drop from end to end. [14] Some heat pipes have demonstrated a heat flux of more than 23 kW/cm 2 , about four times the heat flux through the surface of the Sun. [ 15 ]
The heat sink thermal resistance model consists of two resistances, namely the resistance in the heat sink base, , and the resistance in the fins, . The heat sink base thermal resistance, , can be written as follows if the source is a uniformly applied the heat sink base. If it is not, then the base resistance is primarily spreading resistance:
It also used a 3.7-inch-thick (9.5 cm) 7075 aluminum ballistic case. Aluminum was used to drastically reduce the bomb's weight and simultaneously provided sufficient radiation confinement time to raise yield, a departure from the heavy stainless steel casing (304L or MIM 316L) employed by other weapon-projects at the time.
