Initially, a rigid tank contains 500L of water at 300°C. By volume, the tank contains60% liquid and 40% vapor. At  the bottom of the tank, as shown, a valve is opened and half of the mass of water is withdrawn which is in the  liquid phase. Heat transfer takes place such that the temperature within the tank is constant. Determine the  heat transfer in kJ required to withdraw half of its mass and maintain its temperature. (Provide Schematic Diagram if applicable)

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.
