Chemical Engineering Thermodynamics
High pressure steam is expanded adiabati-cally and reversibly through a well insulated turbine, which produces some shaft work. If the enthalpy change and entropy change across the turbine are represented by ΔH and ΔS respectively for this process:

Δ H ≠ 0 and ΔS ≠ 0
Δ H ≠ 0 and ΔS = 0
Δ H = 0 and ΔS ≠ 0
Δ H = 0 and ΔS = 0
