Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.

2.2 A metal block is riding a conveyor as it travels through a tunnel type furnace and is subjected to a gradually increasing temperature. With respect to speed of travel, the surrounding temperature of the metal block (i.e. the furnace interior) increases by: T = 50°C + 10°C/min. Where, T furnace temperature in °C. 50°C is the atmospheric temperature at the furnace entry. Draw your best guess of the metal temperature vs. time on a graph for 60 min. from start.
