An experiment to measure the thermal conductivity of food formulations was carried out by measuring the surface temperature of the food formulations which were formed into a flat plate with a thickness of 7 mm. It is found that at steady-state conditions, there is a temperature difference of 30 ° C between the two surfaces, the heat transfer rate per unit area of 2450 W / m2 is measured near the center of the two surfaces. Calculate: the thermal conductivity of the product, = W / m ° C
