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.

Question

If 10kg of water at 920kPa pressure and at 60°C is heated to
boiling point, then to dry saturated steam and then to
superheated steam at a temperature of 210°C, determine:

2.2.2 the latent heat;
2.2.3 the heat supplied to superheat the steam
(Cp = 2.1kJ/kgK);
2.2.4 the total heat required for superheating the water.
