Second Law analysis of Gas Power Cycles, used in practice, is presented. The objective of this analysis was to compute the available energy degradations and entropy creations caused by the departures from the ideal standard such as finite temperature difference in heat exchange processes and fluid friction in different pieces of equipment. Various combinations of Brayton cycle with varying irreversibilities were analysed. It was demonstrated that the decrease of shaft work output from ideal maximum, available energy degraded and the increase in the unavailable energy of the Universe are all equal. This analysis will facilitate the selection of combination of equipment which gives more favourable work output.
