A steel flask of 0.04 m³ capacity is used to store Nitrogen at 120 bar and 20°C. The flask is protected against excessive pressure by a fusible plug which will melt and allow the gas to escape if the temperature is too high. A. How many kilogram of Nitrogen will the flask hold at the design conditions? B. At what temperature in °C must fusible plug melt in order to limit the pressure of flask to a maximum of 150 bar?

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.
