Chapter 15 Steady Heat Conduction3-91A spherical ball is covered with 1-mm thick plastic insulation. It is to be determined if the plastic insulation on the ball will increase or decrease heat transfer from it. Assumptions1Heat transfer from the ball is steady since there is no indication of any change with time. 2 Heat transfer is one-dimensional since there is thermal symmetry about the midpoint. 3 Thermal properties are constant. 4 The thermal contact resistance at the interface is negligible.
