Steam is flowing through a pipe with a closed valve which feeds into a rigid tank which has a volume of .4 cubic meters. The steam is at 1.4 MPa and 300C. The tank is initially filled with saturated vapor steam at 350 kPa. The valve is opened and steam flows into the rigid tank until the pressure is 1.4 MPa. Determine the mass of steam added to the tank and the final temperature of the tank.

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.
