A steam turbine is to operate on a simple regenerative cycle. Steam is supplied dry saturated at 40 bar, and is exhausted to a condenser at 0.07 bar. The condensate is pumped to a pressure of 3.5 bar at which it is mixed with bleed steam from the turbine at 3.5 bar. The resulting water which is at saturation temperature is then pumped to the boiler. For the ideal cycle sketch the process on the T-s diagram and calculate, neglecting feed pump work, The amount of bleed steam required per kg of supply steam The thermal efficiency of the plant The specific steam consumption
