A simple Bryton cycle with air as the working fluid has a pressure ratio 12. \( \rightarrow \) determine the thermal efficiency, network output, the air temperature at the turbine exit and the produced and supplied work in \( (\mathrm{KJ} / \mathrm{Kg}) \) Assumption: 1- Steady state operating condition 2- Air-Standard assumption are applied 3- Kinetic and potential energy are negligible 4- Air is an ideal gas with variable specific heat Assume: - P1 \( =100 \mathrm{kpa} \) - \( \mathrm{T} 1=27 \mathrm{c}=300 \mathrm{k} \) - \( \mathrm{Rp}=12 \) - \( \eta_{c}=86 \% \) - \( \eta_{T}=90 \% \) - \( \mathrm{T} 3=1027 \mathrm{c}=1300 \mathrm{k} \) Solve it in EES program using cold air assumption
