Question

Superheated steam at 82 bar, 400 0C, is throttled (∆H = 0) by a valve to 41 bar before entering a turbine and exiting as a saturated vapor. If the turbine is isentropic (∆S = 0), report results for T, P, H, S for the 3 states b.) (5 pts) Compute the output work of the turbine, ∆H23, in J/mol. c.) (10 pts) What is the change in Gibbs free energy for the overall 2-step process, in kJ/kg? d.) (15 pts) 80% of the work from part (b.) is converted into heat to heat ethane gas. In other words, Q_C2H6=-0.80W_turb→〖∆H〗_C2H6=-0.80〖∆H〗_23
