Steam enters the high-pressure turbine of a steam power plant that operates on the ideal reheat rankine cycle at 1000 psia and 900°f and leaves as saturated vapor. steam is then reheated to 800°f before it expands to a pressure of 1 psia. heat is transferred to the steam in the boiler at a rate of 6 × 10^4 btu/s. steam is cooled in the condenser by the cooling water from a nearby river, which enters the condenser at 45°f. use steam tables. determine the following: (a) the pressure at which reheating takes place. psia (b) the net power output and thermal efficiency. % (c) the minimum mass flow rate of the cooling water required. lbm/s
