Saturated liquid Propane flows in to a valve. It enters at 375 psia, and leaves at 15 psia.

Saturated liquid Propane flows in to a valve. It enters at 375 psia, and leaves at 15 psia. Mass flow through the valve is 1.25 lbm/hr. Use EES and ‘Propane’ as your fluid. This new device replaces the valve with a ‘magic’ isentropic device. Assuming the device operates at steady state, and PE and KE terms are insignificant, calculate how much power could be generated by the device (hp)?
