pipe with an outside diameter of 2.7 inches. insulate with a 2 inches. layer of asbestos (ka = 0.396 btu-in./hr-ft-F), followed by a layer of cork 1.5 inches. thick (kc = 0.30 btu-in/hrft-F). if the temperature of the outer surface of the cork is 91 F, calculate the heat lost per 100 ft of insulate pipe. The temp of the inner surface of the pipe is 275 F.
