A food product with 80% moisture content is being frozen in a 5 cm-diameter can. The product density is 1000 kg/m3, the thermal conductivity is 1.0 W/(m K), and the initial freezing temperature is -2°C. After 12 h in the -30°C freezing medium, the product temperature is -10°C. Estimate the convective heat-transfer coefficient for the freezing medium. Assume the can has infinite height.
