Problem
1. A turbine receives steam at 3000 kPa, 500oC and has two exit flows, one at 1000 kPa, 350oC with 20% of the flow and the remainder at 200 kPa, 200oC. Find the isentropic and second-law efficiencies.
2. Steam enters a turbine at 25 MPa, 550oC and exits at 5 MPa, 325oC at a flow rate of 70 kg/s. Determine the total power output of the turbine, its isentropic efficiency, and its second-law efficiency.
The response should include a reference list. Double-space, using Times New Roman 12 pnt font, one-inch margins, and APA style of writing and citations.
