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.

Q/ A radiator of steam heating system has a volume of 0.2 m'. When the radiator is filled with saturated steam at a pressure of 1.5 bar all valves are closed. After a period of time the pressure inside the radiator becomes 1.4 bar due to heat lost to surrounding air. Calculate: 1- mass of steam within the radiator. 2- mass and volume of liquid water at the final state. 3- mass and volume of vapor at the final state. From steam tables, at 1.5 bar, Since all valves are closed the specific volume of steam remains constant as heat is lost. At 1.4 bar, Since v2 < v g at 1.4 bar the steam becomes wet.
