For air: R = 0.287 kJ/kgK, Cp=1.005 kJ/kgK, For an ideal gas undergoing an isentropic process: Cv = 0.718 kJ/kgK, k=1.40 (1/3)= V₂ V₂ k-1 P₂ P₁₂ (k-1)/ k 1. Steam enters an adiabatic turbine at 7 MPa and 550 °C and leaves at 400 kPa. If the turbine delivers 670.7 kJ/kg of work during this expansion process, determine the entropy change of steam per unit mass.

please please my quest.

For air: R = 0.287 kJ/kgK, Cp=1.005 kJ/kgK, For an ideal gas undergoing an isentropic process: Cv = 0.718 kJ/kgK, k=1.40 (1/3)= V₂ V₂ k-1 P₂ P (k-1) / k 1. Steam enters an adiabatic turbine at 7 MPa and 550 °C and leaves at 400 kPa. If the turbine delivers 670.7 kJ/kg of work during this expansion process, determine the entropy change of steam per unit mass.
