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.

An insulated, vertical piston–cylinder device is purchased from a manufacturer. Upon purchase, it contains 3 kg of water at precisely 20 degrees celcius. The mass of the piston is such that it maintains a constant pressure of 300 kPa inside the cylinder. Liquid water at 2 MPA and 873.15 Kelvin is allowed to enter the cylinder from a supply line until the instant that the last drop of liquid in the cylinder vaporizes (saturated vapor). Find the mass of the steam that has entered [kg].
