Problem
A two-stage compressor in a gas turbine brings atmospheric air at 100 kPa, 17oC to 500 kPa, then cools it in an intercooler to 27oC at constant P. The second stage brings the air to 2500 kPa. Assume both stages are adiabatic and reversible. Find the combined specific work to the compressor stages. Compare that to the specific work for the case of no intercooler (i.e., one compressor from 100 to 2500 kPa).
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.
