A 10 cm diameter orange has properties similar to those of water. The orange was at 20 o C. and suddenly, it is subjected to refrigerator air of 4 o C. The air circulation in the refrigerator results in the air velocity over the orange surface at 0.1 m/s. Determine the center and the surface temperatures of the orange after 5 min. With this air circulation, free convection may be negligible. Radiation is also negligible.
