A THERMODYNAMICS PROBLEM?

10. A polytropic process of air from 150 psia, 300 F, and 1 ft^3 occurs to p2= 20 psia in accordance with pV^1.3 = C. Determine (a) t2 and v2, (b) ΔU, ΔH, and ΔS, (c) ∫pdV and - ∫Vdp. (d) Compute the heat from the polytropic specific heat and check by the equation Q = ΔU + ∫pdV. (e) Find the nonflow work and (f) steady flow work for ΔK = 0.
