How does radius affect capillary rise?
As r is in the denominator, the thinner the space in which the liquid can travel, the further up it goes. Likewise, lighter liquid and lower gravity increase the height of the column. Thus for a 2 m (6.6 ft) radius glass tube in lab conditions given above, the water would rise an unnoticeable 0.007 mm (0.00028 in).
What happens to the capillary rise of a liquid when the diameter of the capillary tube increases?
The capillary rise is inversely proportional to the tube radius. It can be also applied to the case where the liquid level in the tube decreases below the outer liquid surface; this situation happens when θ=90°.
How much effect would doubling the cross sectional area of a capillary tube have on the height to which a liquid would rise in the capillary?
the height to which water will rise in a capillary tube of cross-sectional area 4A will be. Cross sectional area increases four times, which means radius gets doubled.
What would happen to the height of the water in the capillary tube?
On one hand, it depends on the diameter of the capillary tube; water will rise higher in a narrower tube. On the other hand, height of water also depends on surface tension. However, surface tension of water varies depending on temperature; when temperature increases, surface tension decreases.
A capillary tube dipped in a body of free water will form a meniscus as the result of the contact angle of water with the walls of the tube. The curvature of this meniscus will be greater (i.e., the radius of curvature smaller) the narrower the tube.
Why does the capillary rise decreases when the diameter is increased?
A thinner tube has less surface area and so the water molecules have less space to fill and that’s why they rise higher in a thin tube then a thick tube. This is the reason why the capilliary rise increase when the diameter of the tube decreases.
What would happen to the height of water in the capillary tube of the sucrose concentration was increased?
Or, (c) What happens to the height of the water when sucrose concentration increases? Possible observations 1: The higher the sucrose concentration, the higher the water rises.
What are the factors affecting the capillary rise of water?
For this study, the factors used to determine capillary rise are the diameter of the capillary tube (representing the diameter of the pores in a soil), the contact angle between the liquid and the surface to which it adheres, the density of the liquid, the viscosity of the liquid, surface tension, and whether or not …
