An experiment was conducted to measure thermal conductivity of a formulated food. The measurement was made by using a large plane plate of the food material, which was 5 mm thick. It was found, under steady-state conditions, that when a temperature difference of 35°C was maintained between the two surfaces of the plate, a heat-transfer rate per unit area of 4700W/m² was measured near the center of either 4.3

An experiment was conducted to measure thermal conductivity of a formulated food. The measurement was made by using a large plane plate of the food material, which was 5 mm thick. It was found, under steady-state conditions, that when a temperature difference of 35°C was maintained between the two surfaces of the plate, a heat-transfer rate per unit area of 4700W/m² was measured near the center of either surface. Calculate the thermal conductivity of the product, and list two assumptions used in obtaining the result. 4.3
