Two rigid tanks A and B are connected by a valve. Tank A contains 0.6 of water at 550 kPa and 38 percent quality. Tank B contains 0.82 of water at 200 kPa and 700 oC. The valve is now opened and the two tanks eventually come to the same state and reach thermal equilibrium with the surroundings at 35 oC. Calculate the followings: a) The final pressure in the system (kPa); b) the amount of heat transfer (kJ). Submit your solution by adding (a) + (b)

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.
