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:?
Answer: Option 2 For a reversible adiabatic process the entropy change is zero since $$dS = \frac{{\delta Q}}{T}$$ But the enthalpy change need not be zero since the internal energy and...
