In a piston cylinder assembly as in the figure, 0.1 m3 of saturated water at 800 kPa pressure is in equilibrium with 0.9 m3 of saturated water vapor. Heat transfer occurs until the temperature inside the cylinder rises to 350 oC. Neglecting the frictional forces between the piston and cylinder: a) Show the process change in T − v and P − v diagrams, taking into account the saturation curves. b) Find the initial temperature of the water. c) Calculate the total mass of water. d) Calculate the volume in the final case.

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.
