A piston-cylinder assembly initially contains 10 MPa pressure and 10 water vapor at 100 oC. Then, heating is carried out for 2 hours with the electric heater, which passes 220 V 20 A current at constant pressure to the water, during which time 7500 kJ of heat is transferred to the environment. Determine the final temperature of the water by showing this process on the T-v diagram.

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.
