Find the required fraction of the extraction flow in turbine

Question

Problem

1. An open FWH receives steam at 1 MPa, 200^oC from the turbine and 1 MPa, 100^oC water from the feed water line. Find the required fraction of the extraction flow in the turbine.

2. A power plant for a polar expedition uses ammonia and the boiler exit is 80^oC, 1000 kPa, and the condenser operates at -15^oC. A single open FWH operates at 400 kPa with an exit state of saturated liquid. Find the mass fraction extracted in the turbine.

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.
