A compressed air tank in a service station has a volume of 10 ft³. It contains air at 70°F and 150 psi (abs.). How many tubeless tires can it fill to 44.7 psi (abs.) at 70°F if each tire has a volume of 1.9 ft3 and the compressed air tank is not refilled? The tank air temperature remains constant at 70°F because of heat transfer through the

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.
