The top cycle of a combined cycle power plant as shown has a
pressure
ratio of 12. Air enters the compressor at 295K at a rate of 12 kg/s
and
is heated to 1100 K in the combustion chamber. The steam in
the
bottom cycle is heated to 350°C and 10 MPa in a heat exchanger,
and
after leaving the turbine, it is condensed at 10 kPa. The
combustion
gases leave the heat exchanger at 390 K.
(a) Assuming that all compression and expansion processes are
isentropic, determine the thermal efficiency of the combined
cycle
(b) Identify and briefly describe at least two applications for
such a combined cycle
