31. If 4 kg of steam 12 bar, 260 deg C expand into the wet region to 90 deg C in a polytropic processwhere pv1.156 = c, find (a) yz, deta H, delta U, delta S, (b) √ pdV, (c)-S Vdp, (d) W for nonflow, and (e) Wfor steady flow if delta K = -3kJ/kg. What does - Vdp represent in this process? (f) Find Q from steadyflow and also from nonflow energy equations. Use Item B 16 (SI).
Please answer (a), (b), (c).
