Consider the wall in the illustration below, the following are parameters used for the composite wall: k= kp = 2K, kg = 8 K.kc = 20K. kp = 15 K, and kg = 35 K. The left face of the wall is maintained at a constant temperature T = 300C and the right-hand surface is exposed to a convective surface. Assuming that the depth of the wall is Depth = 100cm find: i. Draw the equivalent thermal network. ii. The 1-D heat transfer rate through the wall? iii. Find T where sections B, D, and E meet. T-300C 4cm 4cm 4cm 1cm 5cm B L 6cm 10cm E 12cm m To -50C W h= 20 k
