Air (use the IG model) enters the compressor of an ideal air
standard Brayton cycle
at 100 kPakPa, 290 KK and a mass flow
rate (m˙m˙) of 4 kg/skg/s . The compressor
pressure ratio is 10. The turbine inlet temperature
is 1500 KK. A regenerator with an effectiveness
of 70%% is incorporated in the cycle. The heat addition
can be assumed to take place from a reservoir
at 1800 KK
1)Perform an exergy inventory of the exergy flow rate from the
reservoir.
Express your answer to four significant figures and include the
appropriate units.
2)Determine the thermal efficiency.
Express your answer to four significant figures.
3)Determine the exergetic efficiency.
Express your answer to four significant figures.
4)Calculate the rate of exergy destruction in the
regenerator.
Express your answer to three significant figures and include the
appropriate units.
