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.

An engineer is investigating objects that can be used as a solar collector. One ofthe objects considered is the object made of aluminum and is coated with leadsulfate. Investigation shows that the reflectivity of this object is 0.2 for radiationat wavelengths less than 3.3 μm and 0.95 for radiation greater than 3.3 μm. Inorder to get better insight into the behavior of the object, as a candidate for asolar absorber, the object is then exposed to two different conditions: a solarradiation (T ~ 5800 K) and a room temperature (T ~ 300 K). What is the energyreflected by the object at these two conditions?
