	Capillary action - Wikipedia, the free encyclopedia
		Capillary action or capillarity is the ability of a narrow tube to draw a liquid upwards against the force of gravity.
		The weight of the liquid column is proportional to the square of the tube's diameter, but the contact area between the liquid and the tube is proportional only to the diameter of the tube, so a narrow tube will draw a liquid column higher than a wide tube.
		A plant makes use of capillary action to draw liquid water into its system, although larger plants require transpiration to move a sufficient quantity of water to where it is required.

	Patent 4272970: Compression refrigeration system
		The capillary tube is positioned in an enclosure and the warm liquid refrigerant coming from the condenser flows into the enclosure in a heat exchange relationship with the capillary tube, enters the capillary tube, and flows to the evaporator.
		A flow tube is positioned in the enclosure having an inlet in communication with the interior of the enclosure and the outlet of the flow tube being connected to the enclosure outlet.
		The capillary tube 22 includes an inlet 34 in communication with the interior of the enclosure 30 for receiving the liquid refrigerant returning from the condenser 18 and an outlet 36 connected to line 24 and thus connected to the inlet of the evaporator 26.

		When such a tube of glass, open at both ends, is placed vertically with its lower end immersed in water, the water is observed to rise in the tube, and to stand within the tube at a higher level than the water outside.
		He considered the capillary phenomena to be of the same kind, but his explanation is not sufficiently explicit with respect to the nature and the limits of the action of the attractive force.
		This expression is the same as that for the rise of a liquid in a tube, except that instead of r, the radius of the tube, we have a the distance of the plates.

	Liquid at Top of Capillary Tube
		There are several competing forces acting on the liquid: (a) the cohesive forces of the liquid (its own attraction to itself) exhibited by the strength of its surface tension, (b) the attraction of the liquid to the inside surface of the tube (sometimes referred to as "wetting"), and (c) the gravity acting on the liquid.
		The height of climb depends on the nature (molecular structure, surface tension, density and viscosity) of the liquid, the inner diameter of the tube, the contact angle between the meniscus and tube wall, and the composition of the tube's inner wall.
		If the capillary is too narrow, viscous drag will slow the filling velocity, and surface tension will be high when the water starts to bulge outwards at the destination end.

	XtremeSystems Forums - Capillary tube
		The capillary tube is used to provide resistance to refrigerant flow, creating a high and low pressure area.
		The capillary tube at the other end of the condenser is a smaller diameter which causes resistance, which creates pressure as more refrigerant is pumped thru.
		So, that spot should be the end of the capillary tube and the begin of the evaporator.

	XtremeSystems Forums - Capillary tube lenght?
		If the system is charged properly (suction line frosted, but compressor warm), and the cap tube is too restrictive, then the high side pressure has been elevated in order to push enough refrigerant through.
		You can shorten the cap tube, which will give you a faster pulldown to the same temperature, OR you can leave the cap tube as is and pull down to a lower temperature.
		Cap tube charts assume you want to pull down the heat load faster, which is the case with "normal" systems.
