Steam exits the boiler at 60 bar, 540°C and undergoes a throttling process to 40 bar before entering the turbine. Steam expands adiabatically through the turbine to 5 bar, 240°C, and then undergoes a throttling process to 1 bar before entering the condenser. Kinetic and potential energy effects can be ignored. Draw a Temperature-Entropy diagram and mark each of the states 2-5 on this diagram. Determine the power generated by the turbine, in kJ per kg of steam flowing. For the valves and the turbine, evaluate the rate of entropy production, each in kJ/K per kg of steam flowing.arrow_forward
