Which of the following would lead to a
reduction in thermal resistance?
In conduction, reduction in the
thickness of the material and an increase in the thermal conductivity.
In convection, stirring of the fluid
and cleaning the heating surface
In radiation, increasing the
temperature and reducing the emissivity
All options are correct
All options are correct
Following steps are used to reduce the
thermal resistance :
In conduction, reduction in the
thickness of the material and an increase in thermal conductivity.
In convection stirring of the fluid
and cleaning the heating surface
In radiation, increasing the
temperature and reducing the emissivity.
Hence, the correct option is (D).
