10-88 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 hcc = hg + hs - hghs 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. | |
