    * Introduction to Conduction

    INTRODUCTION TO CONDUCTION Conduction is one of the three basic modes of heat transfer. The two other modes are convection and radiation. Thermal conduction takes place in solids and stationary fluids adhered to the solid surface. But the heat transfer by conduction in fluids is small because of smaller value of conductivity. Temperature difference is the […]

    INTRODUCTION TO HEAT TRANSFER Like transfer of a Government employee from one place to another place, heat transfer is heat in motion from one body to another body. The driving force for heat transfer is temperature difference.Heat flows from a body at higher temperature to a body at lower temperature. Thus it is an irreversible […]

    *Introduction to Radiation

    INTRODUCTION TO RADIATION  Radiation is heat transfer by electromagnetic rays (EMR). These EMR does not need a medium. These EMR are SELF-PROPAGATING WAVES which can travel in vacuum or in a matter medium. These EMR move with the velocity of light 3 x 108 m/s . These EMR are mostly invisible. Order of decreasing energy is  gamma […]
