A metal rod, 12 cm long and 2.0 cm in diameter, is lagged so that no heat escapes from its sides. A steady heat flow of 36.9 Joules per second is applied at one end and when steady thermal conditions have been established it is found that the temperature of the hot end is 90 OC and the temperature of the other end is 20 OC. Determine the thermal conductivity (in W m-1 K-1) of the metal.
