Q4) Determine the specific work output, specific fuel consumption and thermal
efficiency of a gas turbine power plant which produce a power output of 20 MW.
The pressure ratio across the compressor is 4. Hot gases enters the turbine at 1100
K, the isentropic efficiencies of the compressor and turbine are 85% and 87%
respectively. Pressure losses across the combustion chamber, heat exchanger air-
side and heat exchanger gas-side are 0.08bar, 0.12bar and 0.04 bar respectively. The
used fuel of LCV= 44000 kJ/kg, the heat exchanger effectiveness of 80%, ambient
conditions are 1.0 bar and 288 K. Air/fuel ratio is 50:1 .
