Natural Convection Cooling of an Orange. An orange 102 mm in diameter having a surface temperature of 21.1°C is placed on an open shelf in a refriger- ator held at 4.4°C. Calculate the heat loss by natural convection, neglecting radiation. As an approximation, the simplified equation for vertical planes can be used with L replaced by the radius of the sphere (M1). For a more accurate correlation, see (S2).

Transcribed Image Text:Natural Convection Cooling of an Orange. An orange 102 mm in diameter
having a surface temperature of 21.1°C is placed on an open shelf in a refriger-
ator held at 4.4°C. Calculate the heat loss by natural convection, neglecting
radiation. As an approximation, the simplified equation for vertical planes can
be used with L replaced by the radius of the sphere (M1). For a more accurate
