- Draw the T-s diagram of the cycle?
- Calculate the cycle efficiency?
In an air-standard Brayton cycle shown in Figure Q2, the air enters the compressor at \\( 0.1 \\mathrm{MPa} \\) and \\( 15^{\\circ} \\mathrm{C} \\). The pressure leaving the compressor is \\( 1.0 \\mathrm{MPa} \\), and the maximum temperature in the cycle is \\( 1100^{\\circ} \\mathrm{C} \\). Assume a compressor efficiency of \80, a turbine efficiency of \85, and a pressure drop between the compressor and turbine of \\( 15 \\mathrm{kPa} \\). The air and combustion products are assumed to have similar thermodynamic properties, where \\( z=1.4, R=0.287 \\mathrm{~kJ} /(\\mathrm{kg} . \\mathrm{K}), c_{v}=0.718 \\mathrm{~kJ} /(\\mathrm{kg} . \\mathrm{K}) \\) and \\( c_{p}=1.005 \\) \\( \\mathrm{kJ} /(\\mathrm{kg} \\cdot \\mathrm{K}) \\).
