HEAT TRANSFER PROBLEM NO 17- An asbestos pad, square in cross section , measure 0.05 m on a side and increases linearly to 0.1 m on the other end ( see the figure given below. the length of the pad is 0.15 m . if the small end is held at 600 k and the larger end at 300 k , what will be heat flow, if the other four sdes are insulated ? the thermal coductivity =0.173 w/mk
