What factors affect the sedimentation rate?

Asked By: briantist Date created: May 03, 2022

In addition to particle size, density and concentration, and fluid viscosity, other less obvious factors affect the sedimentation rate. These include particle shape and orientation, convection currents in the surrounding fluid, and chemical pretreatment of the feed suspension.2 Feb 2011

How does density affect settling rate?

Asked By: Adriaan Stander Date created: May 04, 2022

The settling rate of a particle depends on its size, shape, and density as well as on the vis- cosity of the fluid through which it is settling. In general, smaller particles have a larger sur- face area to mass ratio, so their settling rates are slowed more by frictional drag than are larger grains.

Does mass affect size?

Asked By: Daniel W. Date created: May 12, 2022

Is mass the same as size? No, mass is different than size or volume. This is because the type of atoms or molecules as well as their density helps to determine the mass. For example, a balloon filled with helium will have much less mass than a similar sized item made of solid gold.

Does size affect buoyancy?

Asked By: BlivetWidget Date created: May 17, 2022

Because the buoyancy of a solid cube of material depends on its density, which does not vary with the size of the object, changing the size of a cube does not affect whether it will sink or float.

Does Weight Affect density?

Asked By: Richie Cotton Date created: May 16, 2022

Density has the components of mass and volume, while weight is concerned with mass and gravity. ... Division is used to find an object's density by dividing the mass over volume, while weight is the product of mass and gravity (by virtue of multiplication). 3. The units to express density and weight also differ.

How does air density affect temperature?

Asked By: Pan Vi Date created: May 10, 2022

Air Density and Temperature This is because warmer molecules of air move faster, creating an expansion effect that decreases air density.

Colder air moves slower, collects together, and sinks with higher density.

This is why warm air rises above cold air..

What are the 4 factors that affect population growth?

Asked By: Maxim Veksler Date created: May 04, 2022

What we might talk about as population size is actually population density, the number of individuals per unit area (or unit volume). Population growth is based on four fundamental factors: birth rate, death rate, immigration, and emigration.

How do density independent factors affect a population?

Asked By: Phuc Tran Date created: May 08, 2022

Density independent factors, in ecology, refer to any influences on a population's birth or death rates, regardless of the population density. Density independent factors are typically a physical factor of the environment, unrelated to the size of the population in question.

Does the density of wood affect how fast it burns?

Asked By: David Basarab Date created: May 09, 2022

The wood sample with highest density was maple with a density of 0.769 gm/cm^3 and maple also had the highest combustion rate with an average time of 3 minutes, 5 seconds before it ignited. My data shows that as the density of the wood gets bigger, the time it takes for the wood to ignite also increases.
