An adiabatic piston-cylinder device equipped with a spring maintains the pressure inside at 300 kPa, when the volume is 0, and in 3 000 kPa, when the volume is 5 m ^ 3. The device connects to a steam supply line at 1,500 kPa and 200 ° C, and at the beginning the volume of the cylinder is 0. Determine the final temperature (and quality, if applicable) when the valve is opened and water vapor is allowed to enter from the supply to the cylinder, until the pressure inside is equal to the one on the line. Also determine the total work performed during this adiabatic filling process.

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.
