problem 3 an air standard gas turbine operates on actual brayton cycle
Problem 3: An air-standard gas turbine operates on actual Brayton Cycle with regeneration. Air enters the compressor at120 kPa and 35 C. The compressor pressure ratio is 12; the maximum cycle temperature is900 C and the cold air leaves the regenerator 11 C cooler than the hot ai rat the inlet of the regenerator. Assuming both the compressor and turbine have85% efficiency,Determine (a) the rate of heat addition and heat rejection for the cycle, (b) the net work output and (c) the mass flow rate if the cycle produces 125 kW of power.
