steam enters the first-stage turbine at 40 bar and 500c with a volumetric flow rate of 90 m3/min. steam exits the turbine at 20 bar and 400c. the steam is then reheated at constant pressure to 500c before entering the second-stage turbine. steam leaves the second stage as saturated vapor at 0.5 bar. for operation at steady-state, and ignoring stray heat transfer and kinetic and potential energy effects, determine the:
