"Adiabatic" indicates that there is No change in entropy due to heat transfer. Therefore that would eliminate the (SQ/T) and leave us with (S2-S2 = Sgen)

2. A closed, adiabatic device claims to derive useful work by expanding 1 kg of steam from 500 C and 20 bar to 100 C and 1 bar. Do you believe this claim? Assume steam is a real fluid following the steam tables in Appendix A.III.

Thanks for the response. There seems to be no indication in the problem statement whether or not the steam is saturated or superheated. The topic I am currently covering in class is Reversible/Irreversible Closed Systems and Unsteady Flow Systems. Do you know what part of the problem statement...

I am completely lost with this problem. How would I go about breaking it up into manageable components that so I won't get lost in the problem? Homework Statement A 2 m3 rigid storage tank containing 10 kg of steam is heated from 300 to 400 C by transferring heat from a hot reservoir at...
