WebThe P-v and T-s diagrams of an ideal Brayton cycle are shown on the left. In an ideal Brayton cycle, heat is added to the cycle at a constant pressure process (process 2-3). q in = h 3 - h 2 = c P (T 3 - T 2) Heat is rejected at a constant pressure process (process 4 -1). q out = h 4 - h 1 = c P (T 4 - T 1) WebUsing these efficiencies helps find the weak points of the cycle and how to use less fuel for more work. Since this cycle relies upon air as the working fluid, there is a pressure ratio that needs to be tracked throughout the cycle. Using the ideal gas law, airflow and properties are able to be fully tracked throughout the cycle.
