    HEAT TRANSFER INTRODUCTION CLASS NOTES FOR MECHANICAL ENGINEERING

     HEAT TRANSFER  INTRODUCTION CLASS NOTES FOR  MECHANICAL ENGINEERING Compare heat transfer with the transfer of a Government employee. Heat transfer is heat in motion. The driving force for heat transfer is temperature difference. Heat flows from a body at higher temperature to a body at lower temperature. It is an irreversible process. Greater is the […]


  • FIN HEAT TRANSFER CLASS NOTES FOR MECHANICAL ENGINEERING

    FIN HEAT TRANSFER CLASS NOTES FOR MECHANICAL ENGINEERING

    FIN HEAT TRANSFER CLASS NOTES FOR MECHANICAL ENGINEERING   Fin is a solid extended surface  or a combined conduction convection system. Heat is transferred  by Conduction within the solid and by convection from the fin surface in a PERPENDICULAR  direction to that of conduction. Finally heat is lost to the surroundings. Fins increase the rate of heat […]
