The diameter of an air compressor cylinder is 140 mm, the stroke of the piston is 180 mm, and the clearance volume is 77 cm². The pressure and temperature of the air in the cylinder at the end of the suction stroke and beginning of compression is 0.97 bar and 13°C. The delivery pressure is constant at 4.2 bar. Taking the law of compression as PV1.3 = C, calculate the volume of air delivered per stroke in liter

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.
