Steam from a turbine with inlet pressure 30 bar and temperature 350°C is bled at 5 bar and 1 barto supply a two-stage regenerator to heat up condensate leaving the turbine at 0.08 bar. In eachstage, the condensate is heated up to the saturation temperature of the bled steam and the bledsteam itself condenses completely. Remember: in a regenerator, there is no contact between thetwo streams, only heat exchange.ofConsider the amount of steam bled at 5 bar and 1 bar, respectively, to be m¡ and m2 kg persteam supplied to the turbine.For the first stage, m¡ kg of bled steam at 5 bar heats each kg of condensate arriving from thesecond stage without any contact (that is, regeneration). Then, m¡ kg of condensate derived fromthe bled steam drains into the steam space of the second stage at 1 bar without heat loss. Thecombined drain from the second stage at 1 bar consists of mi+m2 kg per kg of steam supplied tothe turbine. The combined drain is cooled to the condenser temperature before being directed tothe condenser. Assume the expansion of steam in the turbine to be isentropic. Sketch the layout for the above processes showing the flow between the turbine, the two-stage regenerator, the drain cooler and the condenser. Sketch the processes on an h-sdiagram.Determine m¡ and m2, respectively the mass of steam bled off at 5 bar and at 1 bar perkg of steam supplied to turbineCalculate thermal efficiency of the overall cycle.
