Determine the power used by pumps, the power produced by the cycle, the rate of heat transfer in the reheater, and the ther- Damug mal efficiency of this system. 10-33 Steam enters the high-pressure turbine of a steam power plant that operates on the ideal reheat Rankine cycle at 6 MPa and 500°C and leaves as saturated vapor. Steam is then reheated to 400°C before it expands to a pressure of 10 kPa. Heat is transferred to the steam in the boiler at a rate of 6 × 104 kW. Steam is cooled in the condenser by the cooling water from a nearby river, which enters the condenser at 7°C. Show the cycle on a T-s diagram with respect to saturation lines, and determine (a) the pressure at which reheating takes place, (b) the net power output and thermal efficiency, and (c) the minimum mass flow rate of the cooling water required. mains the same
