Question
Transcribed Image Text:Q5/. A gas turbine power plant ,The pressure of air entering the
compressor at( 1 bar), and minimum and maximum cycle temperatures
are 25°C and 1250°C. Compression is carried out in two stages with
perfect intercooling, the compressor ratio(3) for each stage. The gases
coming out from HP. turbine are heated to 1250°C before entering into
L.P. turbine. The expansions in both turbines are arranged in such a way
that each stage develops same power. Assuming compressors and
turbines isentropic efficiencies as 83%,
(1) determine the cycle efficiency assuming ideal regenerator. Neglect the
mass of fuel.
(2) Find the power developed by the cycle in kW if the airflow through
the power plant is 16.5 kg/sec.
