3.) Steam with an enthalpy of 2843.5 KJ/kgundergoes a constant pressure process at 0.9 MPa until the enthalpybecomes 2056.1 KJ/kg. What is the
(a) initial temperature of the steam (b) Change ininternal energy (c) Change in entropy and (e) Heat?
4.)Steam at 200 deg. C with an entropy of 5.6105 KJ/kg-Kexpands isothermally to 0.515 MPa. For 5kg total mass, determinethe following:
(a) ∆S (b) ∆H (c) ∆U (d) Heat (e) Work for a non-flowprocess (f) Work for a steady flow process.
