  • Boiler and Condenser Pressures - Rankine Cycle | nuclear …

    Boiler and Condenser Pressures – Rankine Cycle. As in the Carnot, Otto, and Brayton cycle, the thermal efficiency tends to increase as the average temperature at which energy is added by heat transfer increases and/or the average temperature at which energy is rejected decreases. This is the common feature of all thermodynamic cycles.
