A film-type condenser consists of a packed bed of 3-cm-diameter spheres with a voidage of 35%. Water sprayed onto the bed at 60° C is used to condense steam entering at the base at a saturation temperature of 100° C. How deep must the bed be to ensure complete condensation of the steam, and what is the outlet temperature of the water? (Use water properties based on the mean of the inlet and outlet water temperatures, and iterate if necessary.)

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.
