Question: Heat is transferred steadily through a 0.2-m thick 8 m 3 4 m wall at a rate of 2.4 kW. The inner and outer surface

Heat is transferred steadily through a 0.2-m thick 8 m 3 4 m wall at a rate of 2.4 kW. The inner and outer surface temperatures of the wall are measured to be 158C and 58C. The average thermal conductivity of the wall is
(a) 0.002 W/m·8C
(b) 0.75 W/m·8C
(c) 1.0 W/m·8C
(d) 1.5 W/m·8C
(e) 3.0 W/m·8C
