WebRankine cycle also works on four major processes. They are-Isentropic compression (process 1-2): Pressure of working fluid increases in this process. Isobaric heat addition (process2-3): High pressure liquid is subjected to heat inside the boiler where it gets converted into steam.The steam exits at high pressure and enters the turbine at point 3. WebThe Brayton cycle is completed in Fig. 4 by a constant pressure process in which the volume of the unit gas mass is decreased (temperature decrease) as heat Q 41 is rejected. Most gas turbines operate in an open cycle mode, in which, for instance, air is taken in from the atmosphere (point 1 in Figs. 1 and 4) and discharged back into the atmosphere (point …
