Question #4 A rigid tank with a volume of 2-m³ initially contains air at 100 kPa and 30 °C. The tank is connected to a supply line through a valve. The inlet air flows at 600 kPa and 25 °C. The valve is now opened, and air enters the tank until the pressure inside the tank reaches the pressure of the inlet supply, at which point the valve is closed. The air temperature at the final state is 77 °C. Determine the entropy generation if atmospheric temperature is 298 K. P₁= 600 kPa T₁= 25°C V= 2 m³ P₁ = 100 kPa T₁=30c lout

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.
