Determination of thermal conductivity. in determining the thermal conductivity of an insulating material, the temperatures were measured on both sides of a flat slab of 25 mm of the material and were 318.4 and 303.2 k. the heat flux was measured as 35.1 w/m2. calculate the thermal conductivity in btu/h-ft-ºf and in w/m-k q = 35.1 w/m 2 t 1 = 318.4 k t 2 = 303.2 k 25 mm
