An ideal cold air-standard Brayton cycle operates at steady state with compressor inlet conditions of 300 K and 100 kPa, turbine inlet temperature of 1800 K. For the cycle, determine the specific net work for the cycle, in kJ/kg, if the pressure ratio for the compressor is 9. You must show all work to get credit for this problem. Also, input your answer for net work below.
