Steam enters the high-pressure turbine of a steam power plant that operates on the ideal reheatRankine cycle at 800 psia and 900 °F and leaves as saturated vapor. Steam is then reheated to 800 deg F beforeit expands to a pressure of 1 psia. Heat is transferred to the steam in the boiler at a rate of 6x104 Btu/s. Steam iscooled in the condenser by the cooling water from a nearby river, which enters the condenser at 45 °F.Show the cycle on a T-s diagram with respect to saturation lines.Determine also the following:the pressure at which reheating takes place,the net power output and thermal efficiency, andthe minimum mass flow rate of the cooling water required.A. 741.0 Ibm/s, 39.4%, 62.23 psiaB. 641.0 Ibm/s, 49.4%, 62.23 psiaC. 641.0 Ibm/s, 39.4%, 62.23 psiaD. 641.0 Ibm/s, 39.4%, 72.23 psia

A steam turbine cycle running on a Rankin cycle between a condenser pressure of 10 kPa and a boiler pressure of 20 MPa, the steam enters the high pressure turbine at a temperature of 600 ° C. The average turbine expands to 800 kPa and then enters the boiler again to be reheated to 500 ° C. The steam leaves the boiler to a low pressure turbine, where it expands to the condenser pressure. If the expansion and compression in the turbine and the pump is isotropic, and the addition of heat is constant pressure, find the efficiency of the cycle.
