Mollier Diagram for Water-Steam

Enthalpy-entropy diagram for water and steam

x = dryness fraction - ratio between water as vapor and water as liquid

The dryness fraction is a parameter defining the state of wet vapour.

1 bar = 10⁵ Pa (N/m²) = 0.1 N/mm² = 10,197 kp/m² = 10.20 m H₂O = 0.9869 atm = 14.50 psi (lb_f/in²) = 10⁶ dyn/cm² = 750 mmHg
1 kJ/kg = 0.4299 Btu/ lb_m = 0.23884 kcal/kg

1st Law of Thermodynamics The First Law of Thermodynamics simply states that energy can be neither created nor destroyed (conservation of energy). Thus power generation processes and energy sources actually involve conversion of energy from one form to another, rather than creation of energy from nothing
2nd Law of Thermodynamics The second law is concerned with entropy, which is a measure of disorder. The second law says that the entropy of the universe increases
