Characteristic length of a cylinder formula
WebThe white region of circle can called as thickness of cylinder. For eg. Outer wall is of 12 mm diameter and if inner is of 10 mm diameter so the thickness of cylinder is 2 mm. … WebThe equation to describe this change in (relatively uniform) temperature inside the object, is a simple exponential one described by Newton's law of cooling . In contrast, the metal sphere may be large, so that the characteristic length is large and the Biot number is greater than one.
