Water is the working fluid in an ideal Rankine cycle withreheat.Superheated vapor enters the turbine at 10 MPa, 320°C,andthe condenser pressure is 8 kPa. Steam expandsthrough the first stageturbine and then is reheated to 320°C before expandingin the second stage turbine. Determine forthe cyclea. the heat addition, in kJ per kg of steam entering thefirst-stageturbine.b. the optimum reheat pressure which results inmaximum thermal efficiency. i.e. plot eficiency vsreheat pressure to get the optimum reheat pressure.Vary the reheat pressure in steps of 1 Mpa initially andthen find the approximate pressure for maximumefficiency.find the optimumpressure.
