Tie lines connect compositions of liquid and vapor phases in equilibrium. Any mixture with an overall composition along a tie line gives the same liquid and vapor compositions. Only the amounts of liquid and vapor change as the overall composition changes from the liquid side of the binodal curve to the vapor side.Jun 4, 2015
How do you tie a line in a ternary diagram?
Quote from the video:
Youtube quote: So here I'm going to choose our first tie line and we're going to draw a parallel to length a C. Now we're going to take our other tie line point and draw a parallel to a B.
What is tie line in phase rule?
A tie-line is a horizontal (i.e., constant-temperature) line through the chosen point, which intersects the phase boundary lines on either side.
What is tie line in graph?
The tie line on a two-component solid- liquid phase diagram is an isothermal line that connects two equilibrium phases and passes through the alloy’s position on the phase diagram when it is in a two-phase field, which intersects the two adjacent solubility curves.
What is a tie line chemistry?
(physical chemistry) A line on a phase diagram joining the two points which represent the composition of systems in equilibrium. Also known as conode.
How do you find the plait point in a ternary diagram?
Take each endpoint and draw a line from it downward, perpendicular to base of the triangle. The extensions from the raffinate side will intersect those from the extract side, and each pair forms a point on the conjugate curve. The final point is the plait point.
How do you find the plait point in a ternary phase diagram?
The point at which the α phase switches to the β phase on the phase envelope is the plait point, which is found by following the tie lines up until a tie line is tangent to the phase envelope boundary. The point of intersection is the plait point.
How do you tie a line?
Quote from the video:
Youtube quote: So I'm going to show you that first suppose you have a alloy composition given by point X and these alloy is then separated into two solid phases alpha and beta.
What is the significance of a tie line on a two component solid liquid phase diagram?
A tie line is another name for an isotherm on a solid-liquid phase diagram. It therefore represents a region of constant temperature.
What is importance of tie line in phase diagram?
The ends of the tie lines show the compositions of the two phases that exist in equilibrium with each other at this temperature. From the diagram we know that alpha and liquid phases will exist.
What is a plait point?
The Plait Point P, is the intersection of the raffinate-phase and extract-phase boundary curves. At this point, the equilibrium phases become coincident and no separation can be made at that point.
What does a ternary diagram show?
A ternary phase diagram shows possible phases and their equilibrium according to the composition of a mixture of three components at constant temperature and pressure.
