What is Viscosity?
Viscosity is a measure of a fluid’s resistance to flow. The SI unit of viscosity is poiseiulle (PI). Its other units are newton-second per square metre (N s m-2) or pascal-second (Pa s.). The viscosity of liquids decreases rapidly with an increase in temperature, and the viscosity of gases increases with an increase in temperature. Thus, upon heating, liquids flow more easily, whereas gases flow more slowly. Also, viscosity does not change as the amount of matter changes, therefore it is an intensive property.
How to Calculate Height of Capillary Rise in Capillary Tube?
Height of Capillary Rise in Capillary Tube calculator uses Height of Capillary Rise = (2*Surface Tension*(cos(Contact Angle)))/(Density*[g]*Radius of Capillary Tube) to calculate 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.
How to calculate Height of Capillary Rise in Capillary Tube using this online calculator? To use this online calculator for Height of Capillary Rise in Capillary Tube, enter Surface Tension (σs), Contact Angle (Φ), Density (ρ) & Radius of Capillary Tube (Rc) and hit the calculate button. Here is how the Height of Capillary Rise in Capillary Tube calculation can be explained with given input values -> 18.84666 = (2*70*(cos(0.5235987755982)))/(0.390476*[g]*1.68).
