0.15 m3 of an ideal gas at a pressure of 15 bar and 552 K is expanded isothermally to 4 times the initial volume. It is then cooled to 290K at constant volume and then compressed back polytropically to its initial state. Calculate the net work done and heat transferred during the cycle

Q: Boiler raises 3.7 kg of water per kg of coal from feed water at 54.5oC,to steam at the pressure of…

A:

Q: Calculate the workdone, heat transfer and change in entropy.  Do not need to solve.  I just need…

A: Now write the expression for the work done.

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.
