It can be shown that the thermal efficiency of a combined gas?steam power plant hcc can be expressed in terms of the thermal efficiencies of the gas- and the steam-turbine cycles as ncc = ng + ns ? ngns Prove that the value of hcc is greater than either of hg or hs. That is, the combined cycle is more efficient than either of the gas-turbine or steam-turbine cycles alone.
