Q.
A two stage air compressor with perfect intercooling is compressing air from 1 bar to 4 bar The volumetric efficiency for the first and second stage compressors are 0.9 and 0.85. Intermediate pressure is based on least work requirement theory. If the stroke ratio of first and second stage compression is 1.2, the ratio of diameter of second to first stage compressor is
Q.
A Brayton cycle power plant uses a regenerator as well as reheater and intercooler. It has two stages of compression and expansion with compression starting at 103 kPa and 23°C. The pressure ratio across the compressor is 4.5. In each combustion chamber 250 kj/kg of heat is added to the air. The increase in temperature of cold air in the regenerator is 18°C. Assume isentropic process in all processes and specific heat to be constant. The total heat rejected is
