Does high silica mean high viscosity

WebViscosity is a measurement of a fluid’s resistance to flow and is measured in Poise or more commonly centipoise (cPs). One cPs is equal to the viscosity of water. From this reference, all other viscosities can be derived. A product like honey would have a much higher viscosity of approximately 10,000 cPs and would WebHigh silica content produces a thick viscous lava that does not flow easily. Low silica content produces a lava that is more fluid and flows more easily. Lava is less dense than the …

Viscosity Definition, Facts, Formula, Units, & Examples

WebViscosity is a material property which describes the resistance of a fluid to shearing flows. It corresponds roughly to the intuitive notion of a fluid's 'thickness'. For instance, honey has a much higher viscosity than water. Viscosity is measured using a viscometer. Measured values span several orders of magnitude. WebThe movement of fluid with high viscosity is sluggish or slow. The movement of fluid with low viscosity is quick. Viscosity is the relative property. If you consider air and water, water has a higher viscosity than air as the air feels less resistance while flowing than water.
