Find:     Considering heat loss from only thecylindrical surface (ignore the ends), which orientation would coolmore quickly? One orientation is for the axis to be parallel togravity and the other perpendicular to gravity.

Assume: 1. For the situation with the axisparallel to gravity, assume the cylinder behaves as a flat verticalplate. 2. Use the properties of unused engine oil (Table A.5) tomodel the oil bath
