Question #153585

Evaluate the nonflow work in terms of p1, V1, p2, V2 of a fluid undergoing a reversible state change in accordance with each of the following defining relations: (a) p = C, (b) V= C , (c) pV = C, (d) pV3 = C, (e) pVlnV = C, (f) p = (200/V2 + 2) psia

Expert's answer

In case of non-flow work,

(a) P=C

Work done= P"(V_2-V_1)"

(b) V=C

Work done= 0

(c)pV=C

W= "P_1V_1 ln(\\frac{V_2}{V_1})"

(d)"PV^3=C"

Work done in this case

"W= \\frac{P_1V_1-P_2V_2}{3-1}"

Other data are not clear
