Unformatted text preview: eciency of a gas turbine. f. Consider an Ideal Reversed Heat Engine (i.e., Heat Pump) with high T reservoir at T h , low T reservoir at T L . q L heat is removed from T L and injected into T h . Uing thermodynamic analysis, nd minimum amount of work needed to operate this heat pump in terms of q L , T h and T L . g. Suppose the world were to replace all coal red power plants with natural gas red power plants, and let us assume that both sets of power plants have identical thermal eciencies. By what fraction would CO2 emission from electricity generation be reduced? h. Problems 3.1 3.8 in Fay & Golomb. 1...
