1.) Steam at 200 deg. C with an entropy of 5.6105KJ/kg-K expands isothermally to 0.515 MPa. For 5kg total mass,determine the following:
(a) ∆S (b) ∆H (c) ∆U (d) Heat (e) Work for a non-flowprocess (f) Work for a steady flow process.
2.) 5 kg/s of steam at 5.9 MPa and 500 deg. Cexpands to 0.9 MPa in a polytropic process wherePV1.26 =C.
Find: (a) final temperature (b) change in internalenergy (c) change in enthalpy (d)change in entropy (d) worknon-flow (e) Heat considering non-flow work
