A steam turbine in a power plant receives steam at 3000 kPa, 500◦C. The turbine has two exit flows; one is 20% of the flow at 1000 kPa, 350◦C to a feedwater heater, and the remainder flows out at 200 kPa, 200◦C. Find the specific turbine work and the specific entropy generation, both per kilogram flow in.
