12.14 Consider steady, adiabatic flow of air through a long straight pipe with A=0 05 m2. At the inlet section the air is at 200 kPa absolute, 60 C, and 146 m s. Downstream at section , the air is at 95.6 kPa absolute and 280 m s. Determine p01 , p02 , T01 , T02 , and the entropy change for the flow. Show static and stagnation state points on a Ts diagram.
