Height of Capillary Rise in Capillary Tube Solution

Follow our step by step solution on how to calculate Height of Capillary Rise in Capillary Tube?

FIRST Step Consider the formula

h Capillary = \frac{2 \cdot σ s \cdot (\cos (Φ))}{ρ \cdot [g] \cdot R c}

Next Step Substitute values of Variables

∴

h Capillary = \frac{2 \cdot 70N/m \cdot (\cos (30°))}{0.3905kg/m³ \cdot [g] \cdot 1.68m}

Next Step Substitute values of Constants

∴

h Capillary = \frac{2 \cdot 70N/m \cdot (\cos (30°))}{0.3905kg/m³ \cdot 9.8066m/s² \cdot 1.68m}

Next Step Convert Units

∴

h Capillary = \frac{2 \cdot 70N/m \cdot (\cos (0.5236rad))}{0.3905kg/m³ \cdot 9.8066m/s² \cdot 1.68m}

Next Step Prepare to Evaluate

∴

h Capillary = \frac{2 \cdot 70 \cdot (\cos (0.5236))}{0.3905 \cdot 9.8066 \cdot 1.68}

Next Step Evaluate

∴

h Capillary = 18.846658631383m

LAST Step Rounding Answer

∴

h Capillary = 18.8467m

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 h_Capillary symbol.

How to evaluate Height of Capillary Rise in Capillary Tube using this online evaluator? To use this online evaluator for Height of Capillary Rise in Capillary Tube, enter Surface Tension (σ_s), Contact Angle (Φ), Density (ρ) & Radius of Capillary Tube (R_c) and hit the calculate button.
