inlet p 03 = 8 atm and T 03 = 1000°K. The mass flow rate of air is<br />
11 kg/s, and compressor and turbine efficiencies are 0.85. Assuming<br />
that y = 1.4, determine the cycle efficiency and the net power<br />
developed.<br />
<strong>13</strong>.8 A Brayton cycle uses air as the working substance. At the<br />
compressor inlet p 01 - 1 atm and T 01 = 300°K, and at the turbine<br />
inlet p 03 = 8 atm and T 03 - <strong>13</strong>00°K. The mass flow rate of air is<br />
11 kg/s, and compressor and turbine efficiencies are 0.85. Assuming<br />
that y = 1.4, determine the cycle efficiency and the net power<br />
developed. Compare the results of Problems <strong>13</strong>.7 and <strong>13</strong>.8.<br />
<strong>13</strong>.9 A Brayton cycle uses air as the working substance. At the<br />
compressor inlet p oj = 1 atm and T 01 = 300°K, and at the turbine<br />
inlet p 03 = 12 atm and T 03 = 1200°K. The mass flow rate of air is<br />
5.8 kg/s, and compressor and turbine efficiencies are 0.85. Assuming<br />
that y varies with average temperature in each process and<br />
using (11.5), determine the cycle efficiency and the net power<br />
developed.<br />
<strong>13</strong>.10 A Brayton cycle uses air as the working substance. At the<br />
compressor inlet p 01 = 1 atm and T OJ = 300°K, and at the turbine<br />
inlet p 03 =10 atm and T 03 = 1400°K. The mass flow rate of air is<br />
5.8 kg/s, and compressor and turbine efficiencies are 0.85. Assuming<br />
that y varies with average temperature in each process and<br />
using (11.5), determine the cycle efficiency and the net power<br />
developed.<br />
<strong>13</strong>.11 A Brayton cycle uses air as the working substance. At the<br />
compressor inlet p 01 = 1 atm and T 01 = 300°K, and at the turbine<br />
inlet p 03 =14 atm and T 03 - 1400°K. The mass flow rate of air is<br />
5.5 kg/s, and compressor and turbine efficiencies are 0.85. Assuming<br />
that y varies with average temperature in each process and<br />
using (11.5), determine the cycle efficiency and the net power<br />
developed.
