With a 50 m^3 capacity, a tank contains steam at 400 degrees Celsius and 4500 kPa. From the tank, steam is vented through a relief valve to the atmosphere until the pressure in the tank falls to 3500 kPa. Assuming the venting process is adiabatic, estimate the steam's final temperature in the tank and the mass of steam vented

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.
