Using Exergetic Efficiencies

Figure P7.115 and the accompanying table provide steadystate operating data for a two-stage steam turbine. Stray heat transfer and the effects of motion and gravity are negligible. For each turbine stage, determine the work developed, in kJ per kg of steam flowing, and the exergetic turbine efficiency. For the overall two-stage turbine, devise and evaluate an exergetic efficiency. Let T₀ = 298 K, p₀ = 1 atm.
