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.

The Louisiana Superdome has an interior volume of 125 million ft3, covered by a 440,000 ft² roof. On a particular day, the interior air pressure gave a manometer reading of 19 inches mercury (pHg = 13.6 g/cm³). Local atmospheric pressure is 102 kPa. 1. kg Calculate the mass of the air inside, assuming an average temperature of 20 °C. 2. kN Calculate the net force applied to the roof by the interior/exterior air (do not account for the weight of the roof). Assume the roof is flat.
