Boiler and Condenser Pressures - Rankine Cycle

Decreasing the turbine exhaust pressure increases the net work per cycle but also decreses the vapor quality of outlet steam. The case of the decrease in the average temperature at which energy is rejected, requires a decrease in the pressure inside condenser (i.e. the decrease in the saturation temperature).The lowest feasible condenser pressure is the saturation pressure corresponding to the
