A proposed method of power generation involves collecting and storing solar
energy in large artificial lakes a few meters deep, called solar ponds. Solar energy
is absorbed by all parts of the pond, and the water temperature rises everywhere.
The top part of the pond, however, loses much of the heat it absorbs to the
atmosphere, and as a result, the cool surface water serves as insulation for the
bottom part of the pond and helps trap the energy there. Usually, salt is planted at
the bottom of the pond to prevent the rise of this hot water to the top.
A heat engine that uses an organic fluid, such as alcohol, as the working fluid can
be operated between the top and the bottom portions of the pond. If the water
temperature is 27°C near the surface and 72°C near the bottom of the pond,
determine the maximum thermal efficiency that this power plant can have. Treat
the cycle as an ideal heat engine.
Would a heat engine operating under these temperature conditions (27°C and
72°C) be…
A standard Carnot heat engine cycle is executed in a closed system between
the temperature limits of 320 and 1350 K, with air as the working fluid. The
pressures before and after the isothermal compression are 150 and 300
kPa, respectively. Sketch the TS diagram for this cycle.
If the net work output per cycle is 0.75 kJ, determine the efficiency of the
cycle and the heat transfer to the air
(working fluid) per cycle.
