A piece of thermal insulation covers a rocket engine with a surface area of 4.5 m^2. The engine operates at a temperature of 6500C. For safety reasons the other side of the insulation needs to be kept at 100C. TO do this it can allow no more than 160,000 Watts of thermal power to pass through the insulation. IF the insulation has a thermal conductivity (k) of .25, how thick must it be?
