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

The more viscous a substance is, the closer together its molecules are, the more energy required to excite the molecules. Therefore, higher viscosity equals a lower excitability.

What viscosity level was the fluid flow rate the highest?
The relationship between radius and fluid flow rate is inversely proportional. As radius goes down, fluid flow rate goes up. The highest fluid flow rate will be at the lowest radius.
What is the relationship between the shear g and the shear rate?
Viscosity is constant to the flow of the fluid.
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 the viscosity affect of lava affect its flow rate?
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 is a sentence for non-newtonian fluids?
A non-Newtonian fluid is a fluid whose flow properties are not described by a single constant value of viscosity. Many polymer solutions and molten polymers are non-Newtonian fluids, as are many commonly found substances such as ketchup, starch suspensions, paint, blood and shampoo. In a Newtonian fluid, the relation between the shear stress and the strain rate is linear, the constant of proportionality being the coefficient of viscosity. In a non-Newtonian fluid, the relation between the shear stress and the strain rate is nonlinear, and can even be time-dependent. Therefore a constant coefficient of viscosity can not be defined. A ratio between shear stress and rate of strain (or shear-dependent viscosity) can be defined, this concept being more useful for fluids without time-dependent behavior.
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

What is the relationship between the shear g and the shear rate?
Viscosity is constant to the flow of the fluid.
Why do some liquids flow more slowly than others?
The viscosity of the fluid controls its flow rate. A higher viscosity reduces the flow.
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

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).
Water has a relatively low viscosity it will what?
allow substances to diffuse through it it moves faster than a liquid with a relatively high viscosity

What is the Formula for calculating heat transfer by convection?
heat rate = characteristic of fluid and structures * area * difference in temperature between surface and bulk fluid
Various drilling mud have the same apparent viscosity at 1022sec-1 but the effective viscosity at other shear rates may vary widely Explain?
Drilling mud is a nonnewtonian fluid. It's a thixotropic fluid and it's apparent viscosity is a function of shear rate and time so at various shear rate and times you will have various viscosities. The molecular structure of these fluids breaks during tention.For further informations you can refer to rheology or fluid mechanics books.
What is the difference between viscosity and hardness?
Viscostity is the thickness of a fluid and hardness is of a solid. for example, u would b measuring the viscosity level difference between ketchup and water. water is thin and it's flow rate is fast but ketchup has high viscosity so it's flow rate is slow -zainab
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.
