Viscosity means how runny it is. Thus a lava with low viscosity will erupt fast and form long, wide spreading lava flows (eg Hawaii) and lavas of high viscosity will erupt slowly and form lava domes (eg Mt. St. Helens).

What affects the speed of lava flows?

The temperature and the silica content will both affect the viscosity of lave which will in turn affect the flow rate (whereby the lower the temperature and the higher the silica content, the higher the viscosity and the lower the flow rate).


How does heat affect lava flow?

Heat effects the flow rate of lava because the hotter the lava is, the less viscous it is which allows it to flow faster than if it had a slow flow rate. If it has a low temperature, then the flow rate will be much slower because it has a high viscosity.


How thick is the lava from a cinder volcano?

The thickness of lava is generally dependent on the eruption rate of the volcano. The flow rate of lava is measured by the lava's viscosity. Highly viscous lava does not flow well or travel great distances. Low viscosity lava can flow for great distances.


What viscosity level was the fluid flow rate the highest?

The fluid flow rate is typically highest at lower viscosity levels. This is because fluids with low viscosity flow more easily and encounter less resistance, allowing for faster flow rates compared to fluids with higher viscosity levels.


How does the viscosity of a fluid affect its rate of convection?

The viscosity of a fluid affects its rate of convection by influencing how easily it can flow. A fluid with high viscosity will flow more slowly, leading to slower rates of convection. Conversely, a fluid with low viscosity will flow more easily, promoting faster rates of convection.

How is viscosity related to flow rate?

Viscosity is a substances resistance to flow. So as the viscosity of a substance increases, the flow rate will decrease.


How does viscosity relate to flow rate?

High viscosity lead to a low flow rate and inverse.


How does temperature affect how well magma will flow?

It affects the rate of flow of the lava. Hotter means faster flow


What is the graph of flow versus viscosity?

The relationship between flow rate and viscosity is typically nonlinear. As viscosity increases, flow rate decreases. This relationship is often visualized as a curve showing the decrease in flow rate as viscosity increases.

How are viscosity and flow rate related?

viscosity is inversely proportional to the flow rate. the actual formula is complex , but higher the viscosity slower will be the flow rate. honey flows slowly and air flows freely because of the above reason.viscosity is also essential,otherwise we would have never been able to use an ink pen.viscosity makes the ink to flow on paper


What does the viscosity of a fluid tell you about it flow rate?

it tells you, the higher the viscosity and the thicker the substance is the lower the flow rate hope this helped!:) :) peace


Relationship between flow time and viscosity?

The higher the viscosity, the lower the flow rate.


What viscosity level was the fluid flow rate the highest?

The fluid flow rate is typically highest at lower viscosity levels. This is because fluids with low viscosity flow more easily and encounter less resistance, allowing for faster flow rates compared to fluids with higher viscosity levels.


What is The rate at which liquids flow is called?

Viscosity is the term.
