Consider a steam power plant using a reheat cycle as shown. Steam leaves the boiler and enters the turbine at $$4$$ $$MPa,$$ $${350^ \circ }C$$ $$\left( {{h_3} = 3095\,\,kJ/kg} \right).$$ After expansion in the turbine to $$400$$ $$kPa$$ $$\left( {{h_4} = 2609\,\,kJ/kg} \right)$$, the steam is reheated to $${350^ \circ }C$$ $$\left( {{h_5} = 3170\,kJ/kg} \right),$$ and then expanded in a low pressure turbine to $$10$$ $$kPa$$ $$\left( {{h_6} = 2165\,kJ/kg} \right).$$ GATE ME 2004 Thermodynamics - Rankine Cycle Question 29 English
