If feed is a subcooled liquid, q>1 (i.e., L' augmented by vapor condensation), "slope" of feed equation is positive; If feed is a superheated vapor, q<0 (i.e., L' decreased evaporation), "slope"

For example, when a subcooled liquid with mole fraction of A=0.4 (point A) is about the condition of the feed mixture, then we can construct the q-line 

Distillation Column ‼️q-Line‼️ The Feed Line (q-line) The parameter q is the mole fraction of liquid in the feed and the slope of the q-line is q / (q.

The y-intercept of the q-line for a subcooled liquid feed is negative O zero positive ; Question: The y-intercept of the q-line for a subcooled liquid feed is negative O zero positive . This problem

Jan 08,  · Y = (q/(q-1))X - (Xf/(q-1)) Pick an arbitary value for X just a little to either side of Xf. You now have two points to draw the q line. You will need to get your hands on a boiling point

If the feed is a mixture if liquid and vapor, "q" is the fraction that is liquid, i.e. q = 1-y, where y is molar fraction of vapor phase in the 

The classical pool boiling curve is a plot of heat flux, q″, in the y-axis versus excess temperature, ΔT = Tw - Tsat in the x-axis. As the value of the excess temperature increases, the curve

The y-intercept of the q-line for a subcooled liquid feed is negative O zero positive ; Question: The y-intercept of the q-line for a subcooled liquid feed is negative O zero positive .

At x=0.5 another small line is drawn that represents the feed or `q' line. subcooled liquid the slope of the feed line is even positive, the same for a 

subcooled liquid Position B: q = 1.0 saturatedliquidsaturated liquid Position C: 0 < q <: 1 mixture of saturated vapor and liquid PositionD:Position D: q = 0 saturated vapor Position E: operating line after crossing the q-line, estimating the last stage if necessary.

These limits are derived when the feed is either a superheated vapor or a subcooled liquid (when the enriching section operating line coincides \\·ith the diagonal line on the x -y diagram). 3. Some conceptual errors will appear in the deri,·at.ion of q-line.

Subcooled flow boiling has various applications in industrial processes, which includes the regasification of liquefied natural gas at the gas terminal. As subcooled liquid enters the inlet, it is heated up by a constant heat flux applied to the wall surface. The model consists of an inlet region, a heating region, and an outlet region

Step 6: Draw the line with slope 0.5 which is the rectifying section OL. Step 7. Draw the stripping section operating line from the Bottoms composition to the intersection of the rectifying section OL and the q-line. y drawing a x Solution: Step 1: From x D locate x 1 and y 1 horizontal line to the equilibrium condition for stage 1.

The y-intercept of the q-line for a subcooled liquid feed is negative O zero positive ; Question: The y-intercept of the q-line for a subcooled liquid feed is negative O zero positive . This problem has been solved! See the answer See the answer See the

Subtract the actual liquid line temperature from the condensing temperature. The answer is the degrees of subcooling the system has. Systems that have no receiver, or any special devices to increase subcooling, should have about 10°F subcooled liquid refrigerant. Systems that use regular receivers will have little or no subcooling.

a) Subcooled liquid Vapor to vapor, liquid to liquid. (d) Dew point vapor However, if the feed condition is fixed, q-line is also fixed and then we.

May 22,  · If the temperature of the liquid is lower than the saturation temperature for the existing pressure, it is called either a subcooled liquid or a compressed liquid. The term

When feed is partially vaporized: Other than saturated liquid (q = 1) and saturated vapor (q = 0) Slope of 'q - line' = ∝ (feed is at its bubble point).

Figure 2: Examples of q-line slopes The q-line (depicted in blue in Figure 1) starts at the x = y line and intersects the starting point of the rectifying section operating line. The parameter q is the mole fraction of liquid in the feed, and the slope of the q-line is q / (q - 1).

So, can we have a condition in which we have subcooled liquid from the receiver flowing into the liquid line? Subcooled liquid and receivers. This question is generally answered as follows: No, except for the minor amount of subcooling generated by static pressure due to the liquid level in the receiver. For example, R-404A liquid will generate
