Height of Capillary Rise in Capillary Tube Formula Elements

Variables
Constants
Functions
Height of Capillary Rise
Height of Capillary Rise is the level to which the water rises or falls in a capillary tube.
Symbol: hCapillary
Measurement: LengthUnit: m
Note: Value can be positive or negative.
Surface Tension
Surface Tension is the property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules.
Symbol: σs
Measurement: Surface TensionUnit: N/m
Note: Value can be positive or negative.
Contact Angle
Contact Angle is an angle that a liquid creates with a solid surface or capillary walls of a porous material when both materials come in contact together.
Symbol: Φ
Measurement: AngleUnit: °
Note: Value can be positive or negative.
Density
Density of a material shows the denseness of that material in a specific given area. This is taken as mass per unit volume of a given object.
Symbol: ρ
Measurement: DensityUnit: kg/m³
Note: Value should be greater than 0.
Radius of Capillary Tube
Radius of Capillary Tube is defined as the distance between the center of the tube to the periphery of tube.
Symbol: Rc
Measurement: LengthUnit: m
Note: Value should be greater than 0.
Gravitational acceleration on Earth
Gravitational acceleration on Earth means that the velocity of an object in free fall will increase by 9.8 m/s2 every second.
Symbol: [g]
Value: 9.80665 m/s²
cos
Cosine of an angle is the ratio of the side adjacent to the angle to the hypotenuse of the triangle.
Syntax: cos(Angle)

How to Evaluate Height of Capillary Rise in Capillary Tube?

Height of Capillary Rise in Capillary Tube evaluator uses Height of Capillary Rise = (2*Surface Tension*(cos(Contact Angle)))/(Density*[g]*Radius of Capillary Tube) to evaluate the Height of Capillary Rise, The Height of Capillary Rise in Capillary Tube formula is defined as the function of surface tension, contact angle, density, density and Radius of capillary. This relation is also valid for nonwetting liquids (such as mercury in glass) and gives the capillary drop. In this case ϕ > 90° and thus cos ϕ < 0, which makes h negative. Therefore, a negative value of capillary rise corresponds to a capillary drop. Note that the capillary rise is inversely proportional to the radius of the tube. Therefore, the thinner the tube is, the greater the rise (or fall) of the liquid in the tube. In practice, the capillary effect for water is usually negligible in tubes whose diameter is greater than 1 cm. Height of Capillary Rise is denoted by hCapillary symbol.
