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.

As shown in the figure below, two reversible cycles arranged in series each produce the same net work, Wcycle. The first cycle receives
energy QH by heat transfer from a hot reservoir at TH-1000°R and rejects energy Q by heat transfer to a reservoir at an intermediate
temperature, T. The second cycle receives energy Q by heat transfer from the reservoir at temperature T and rejects energy Qc by
heat transfer to a reservoir at Te - 500°R. All energy transfers are positive in the directions of the arrows.

The manufacturer of the device claims that it accepts a heat transfer at a rate of QH = 3.0 kW from a low-grade source of geothermal heat at TH = 80ºC and rejects heat at rate QC to the atmosphere at TC = 20ºC. The device operates at steady state and produced work at a rate of W= 2.5 kW. There are no other heat or work transfers from the device. a.) What is the rate at which the device rejects heat to the atmosphere, QC ? b.) Is this device possible? Justify your answer using an entropy balance.
4. What is the second law of thermodynamics, give its Clausius and Kelvin-Planck statements and justify on their basis why a perpetual motion machines that extracts heat from ambient environment to do work is not feasible. What is difference between reversible and an internally reversible process, and why are most actual processes considered irreversible. Numerical:
A fluid at 0.5 bar occupying 0.08 m3 is compressed reversibly to a pressure of 10.9 bar and specific volume of 0.6 m3/kg according to the law pvn = c. The fluid then expands reversibly according to the law pv2 = c to 1.6 bar. A reversible cooling at constant volume then restores the fluid back to initial state. Calculate the net work for the process in Joules.
