Explanation:
The Mollier diagram is a graphical representation of the thermodynamic properties of steam. It is also known as the enthalpy-entropy diagram or the H-S diagram. The diagram is commonly used in the field of thermodynamics to analyze and visualize the properties of steam.
Dryness fraction is defined as the ratio of the mass of dry steam to the total mass of steam in a mixture. It is a measure of the quality of steam. The dryness fraction varies from 0 to 1. At a dryness fraction of 0, the steam is completely wet, and at a dryness fraction of 1, the steam is completely dry.
Dryness fraction lines on the Mollier diagram represent the constant dryness fraction lines. These lines are useful in determining the thermodynamic properties of steam at a constant dryness fraction. The dryness fraction lines are almost straight lines on the Mollier diagram, except for some regions where they converge.
The convergence of the dryness fraction lines occurs at the critical point of steam. The critical point is the point at which the liquid and vapor phases of steam become indistinguishable. At this point, the dryness fraction of steam is 1, and the temperature and pressure are the critical temperature and critical pressure, respectively.
Therefore, the correct answer is option B, which states that the dryness fraction lines converge at the critical point of steam.
