Estimate the convective heat-transfer coeffi cient on the outside of oranges (external diameter = 5 cm) when submerged in a stream of chilled water pumped around the orange. The velocity of water around an orange is 0.1 m/s. The surface temperature of the orange is 20°C and the bulk water temperature is 0°C.
