Introduction Heat Transfer can be defined as the transfer of heat energy between the system and the surrounding due to temperature difference. Heat on its own will always flow from a body at a higher temperature to a body at a lower temperature

Modes of Heat Transfer Whenever any temperature difference exists heat is transferred from the body at a higher temperature to a body at the lower temperature. Various Modes of Heat Transfer are: (1) Conduction (2) Convection (3) Radiation
