WebAir is used as the working fluid in a simple ideal Brayton cycle that has a pressure ratio of 12, a compressor inlet temperature of 300 K, and a turbine inlet temperature of 1000 K. Determine the required mass flow rate of air for a net power output of 70 MW, assuming both the compressor and the turbine have an isentropic efficiency of 85 ... 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) WebNov 1, 1990 · The optimum pressure ratio for maximum work and efficiency is similarly affected by the parameters, although the regenerator has a greater effect than the receiver. ready sprayer 1002rs
