Required information Problem 09.042 - Piston air compression A piston-cylinder device initially contains 5.00 L of air at 100 kPa and 25°C. Air is now compressed to a final state of 600 kPa and 150°C. The useful work input is 1.2 kJ. Assume the surroundings are at 100 kPa and 25°C. Air V₁ P₁ = 100 kPa T₁ = 25°C Problem 09.042.b - Minimum work of piston air compression Determine the minimum work that must be supplied to accomplish this compression process. (Round the final answer to three decimal places.) The minimum work that must be supplied is 0.371 kJ.

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.
