Specific Gravity And Viscosity Of Liquids

Jun 07, 2011 Specific Gravity And Viscosity Of Liquids. Specific gravity is the heaviness of a substance compared to that of water, and it is expressed without units. In the metric system specific gravity is the same as in the English system. If something is 7.85 times as heavy as an equal volume of water (such as iron is) its specific gravity is 7.85.

Dec 28, 2020 Viscosity is a measure of a fluid’s resistance to flow. It can also be thought of as a measure of a fluid’s thickness or its resistance to objects passing through it. The greater the resistance to flow, the higher the viscosity, so in the previous example, the syrup has a higher viscosity than water. 00:00. 00:02 12:50.

Double-gap systems [14] are a special form of concentric cylinders, specially devised for measuring low-viscosity liquids. The cup is not a hollow cylinder, nor is the measuring bob a solid body. A second cylinder is placed in the center of the cup and the bob is shaped like an inverse cup that turns in the ring-shaped gap between the cup’s ...

Dec 06, 2020 Liquid viscosity is a measure of the internal friction of a liquid. Liquids with high viscosities flow slowly, whereas low viscosity liquids flow quickly. Lava has a relatively high viscosity; water has a relatively low one. You can measure the viscosity of a liquid by measuring the velocity of a sphere as it falls through the liquid.

Viscosity. Viscosity is perceived as 'thickness' or resistance to pouring, but there is more to viscosity than this. All fluids have an internal friction between molecules, which determines how well fluid flows. Due to this internal friction, energy is required to move the liquid and viscosity is the measure of the resistance to flow.

Oct 24, 2018 Viscosity is the measure of a material’s resistance to motion under an applied force. There are several formulas and equations to calculate viscosity, the most common of which is Viscosity = (2 x (ball density – liquid density) x g x a^2) (9 x v), where g = acceleration due to gravity = 9.8 m/s^2, a = radius of ball bearing, and v = velocity of ball bearing through liquid.
