The tank contains 2kg of water at 20C, 1 atm. The tank is heated. When the tank pressure reaches 300kpa, the valve opens and steam starts escaping. Heating continues and steam continues to escape while the pressure remains constant until half of the mass escapes. At this time the tank is filled with saturated vapor at 300 kpa, and the valve closes. Question: Determine the volume of the tank and the amount of supplied heat.

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.
