Ice balls of 10 mm diameter at – 30°C are exposed to an air
current at 15°C with a convection heat transfer coefficient of 200
W/m2 -K. Determine the time when the surface layer will begin to
melt. Also determine the center temperature. Use the following
property values: density = 920 kg/m3 , specific heat 2040 J/kg-K,
thermal conductivity = 2.00 W/m-K.
