Q Line For Mccabe Thiele - Student - Cheresources.com Community

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

Is the liquid subcooled in the condenser?

How many degrees is the liquid subcooled in the condenser? Therefore, the liquid must be subcooled to at least 97 degrees to prevent liquid line flash gas. This means the system would need at least 8 degrees (105 degrees - 97 degrees) of condenser subcooling to prevent liquid line flashing before getting the metering device.

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).

What is Saturated and Subcooled Liquid - Definition

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

Subcooling - Wikipedia

Subcooling. The term subcooling (also called undercooling) refers to a liquid existing at a temperature below its normal boiling point. For example, water boils at 373 K; at room temperature (293 K) the water is termed "subcooled". A subcooled liquid is the convenient state in which, say, refrigerants may undergo the remaining stages of a

Subcooling | Industrial Controls

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.
