17. During a polytropic process 10 1b/sec of oxygen expand reversibly from 1500R to 1000R, the expansion ratio being 1=V/V1-4. For both nonflow and steady flow (APE=0, AKE=0) processes, compute (a) the exponent n (b) AU, AH, and AS, (C) S pv and -fvdp. (d) W and Q. Ans(a) n=1.292 (b) -786.9 Btu/sec, -1097 Btu/sec, 0.1158Btu/sec-R (d)1063.93Btu'sec, -1379.6Btu/sec (d) Q=277.43Btu/sec
