Why does a pyroclastic flow travel more quickly than a lava flow?
A lava flow flows as a viscous liquid, rather like molasses only thicker. A pyroclastic flow is a mixture of ash, gas, and rock fragments and is not significantly affected by viscous forces that would slow it down. It moves like an avalanche or thunderstorm downburst rather than a liquid.
What makes a fluid more viscous than others?
The ability of a liquid to resist flow because of its internal property is viscosity. Viscous liquid refers to liquids that are supercooled, highly viscous, and able to form a glass all at the same time.
What is a non viscous flow?
Viscosity denotes opposition to flow.
Is felsic lava thick and sticky?
It isn't slimy. It is viscous when molten, proportionally to the silica content, but is not at all slimy even when solid. Lava-flow surfaces may become slimy with algae in certain situations - but that's a different matter!
Why does pyroclastic flow travel faster than a lava flow?
Lava is a very viscous liquid, meaning it will resist flowing rather like syrup. Lava flows are often slowed even more as they form a crust of solid rock. A pyroclastic flow is a different matter; it is a dense cloud of hot ash, rock, and gas, behaving more like an avalanche than a flowing liquid. Pyroclastic flows are not slowed by viscous forces.
What are the relationship between viscosity and time of flow?
When a liquid is heated, it will generally become less viscous.
What is the definition of viscous drag in a liquid?
It is the '''''resistance''''' to flow in a liquid.
What does viscosity mean for a liquid?
It is the ability of the liquid to flow. The higher the viscosity, the less the ability to flow. For example, oil is more viscous than water; honey is more viscous than oil.
What is the speed of a liquid?
I think you may be talking about viscosity. The viscosity of a liquid is its resistance to flow, or its thickness. A less viscous liquid will flow more quickly than a more viscous fluid. As an example, water has very low viscosity and molasses has a high viscosity.
What makes stocks liquid?
Stock's flow means a slow flow of very viscous liquid when non-linear inertia's component can be neglected with respect to the value of friction force in the liquid. Re<<1

What is an example of high and low viscous material?
Viscosity is a measurement of how much a liquid resists flow or deformation -- viscous liquids tend to move more slowly than non-viscous liquids. An example of a highly viscous liquid might be honey or molasses; vinegar and water have low viscosity.
What is the difference between viscous and non viscous fluid flow?
it mean that it can not be compressed
