How Heat Is Transferred From One Body To Another
Heat Transfer According to Vedat S. (2000) heat transfer is a sub field of mechanical engineering in which the transfer of heat between different item and objects with or without any medium is studied. Heat transfer between two bodies take place as a result of difference in temperature between two bodies. Heat always transfers from region of high potential to the region low potential. In general the motion of heat in or out of the systems is mainly deal by the laws of thermodynamics. According to C.P. Kothandaraman (2006) there two thermodynamics laws which are used in heat transfer and they are first and second law of thermodynamics. First law of thermodynamics establish a relationship between the energy generated, heat flow and energy stored in any thermodynamics system. For any closed system this law say that the total energy generated inside a system is equal to the heat transfer through that system plus the internal energy of that system. Second law of heat transfer shows
