Correct option is D
Enthalpy-Entropy Diagram (H-S Diagram)
Key Features:
Purpose:
Graphical representation of thermodynamic properties of a substance (e.g., steam, refrigerants).
Plots enthalpy (H) on the y-axis and entropy (S) on the x-axis.
Applications:
HVAC systems: Analyzing refrigeration cycles.
Power plants: Steam turbine efficiency calculations.
Chemical engineering: Process optimization.
