Superheated steam available at \(800 \mathrm{psia}\) and \(600^{\circ} \mathrm{F}\) is to be expanded to a pressure of \(150 \mathrm{psia}\) at the rate of \(100,000 \mathrm{lb} / \mathrm{hr}\). Calculate with a simulator the exit temperature, phase condition, and \(\mathrm{Hp}\) recovered for an:

(a) Adiabatic valve

(b) Isentropic expansion turbine

(c) Expansion turbine with an isentropic efficiency of 75\%
