a) Explanation Show the simple Brayton cycle, and with air as the working fluid on T − s diagram as in Figure (1). For the given Brayton cycle with air as the working fluid T i , and P i are the temperature at i t h state and pressure at i t h state respectively. Write the temperature and pressure relation ratio for the process 1-2. T 2 = T 1 ( P 2 P 1 ) ( k − 1 ) / k T 2 = T 1 ( r p ) ( k − 1 ) / k (I) Here, the specific heat ratio is k and pressure ratio is r p . Write the temperature and pressure relation ratio for the process 3-4. T 4 = T 3 ( P 4 P 3 ) ( k − 1 ) / k T 4 = T 3 ( 1 r p ) ( k − 1 ) / k (II) Write the expression of net specific work produced by the Brayton cycle ( w net ) . w net = w turbine − w compressor w net = c p ( T 3 − T 4 ) − c p ( T 2 − T 1 ) (III) Here, specific heat at constant pressure is c p b) To determine The net specific work produced by the Brayton cycle using variable specific heats.
