piece of beef steak 7 cm thick will be frozen in the freezer room -35 ° C. This product has a moisture content of 73%, a density of 970 kg / m³, and a thermal conductivity (frozen) of 1.1 W / (m K). using the Plank equation. This product has an initial freezing temperature of -1.75 ° C, and the movement of air in the freezing room gives a convective heat transfer coefficient of 10 W / (m² K). tf =

Estimate the thermal conductivity of the meat at 35 ° C. (Air content = 62.0% wet basis). Thermal conductivity of the material = AnswerW / m ° C
