# When is the particle density equal to the bulk density?

# What is Bulk density power?

Answer Bulk density a property of particulate materials. It is the mass of many particles of the material divided by the volume they occupy. The volume includes …the space between particles as well as the space inside the pores of individual particles. Bulk density is not an intrinsic property of a material; it can change depending on how the material is handled. For example, grain poured in cylinder will have a particular bulk density; if the cylinder is disturbed, the grain particles will move and settle closer together, resulting in a higher bulk density. For this reason, the bulk density of powders is usually reported both as "freely settled" and "tapped" density (where the tapped density refers to the bulk density of the powder after a specified compaction process, usually involving vibration of the container.)

# Maximum bulk density can be occur?

bulk density depend on that material from which soil formed. so maximum bulk density depend on particle density of that mineral. Therefore,we can only tapped the soil upto per…ticle density. so maximum bulk density may be occur at equal to paricle density.

# What is soil bulk density?

Soil bulk density indicate a soil's compaction characteristic. This is calculated by dividing the dry weight of the soil by its volume.

# What is the unit for bulk density?

gram/cm^3

# How does tap density and bulk density differs?

Tap density (or packed density) refers to the density a volume a specific weight of powder has after it has been settled or packed until nofurther volume change is observed. … Apparent (or bulk or Scott density) is the density of a weight of a certain volume of powder. The powder is allowed to flow freely and gently into a container of a known volume. The difference is tap density is the density of a compacted powder and bulk density is the density of a powder with no compaction at all. Both methods use different apparatus but use the formula of density = mass/volume.

# Bulk density of coking coal?

Bulk density of coking coal depends on many factors. But commonly it can be told as 0.8 T/Cu.M.

# How do you find porosity of a soil when all you are given is the dry density and the particle density of the soil.. and can you find bulk density with just this info?

Concerning the second Question: "Can you find bulk density with just this info?" Purely on mathematical insight and analysis: Yes, you should be able to find the bulk densi…ty of dry soil, given the 'dry overall' and the 'particle' densities. When wet, there is not enough 'given' Also some should be known about the (or your) definition of porosity

# What is Bulk density?

Bulk density is defined as the weight per unit volume of material. Bulk density is primarily used for powders or pellets. The test can provide a gross measure of particle size… and dispersion which can affect material flow consistency and reflect packaging quantity. Bulk Density ASTM D 1895 B

# What is the Bulk density of refractory brick?

# What is the applications of bulk density?

The method is to be used for milk powders and all other dried milk products.

# What is the bulk density of wheat?

The bulk density of wheat varies depending on it's type, condition, age , etc. The short answer is about 720-780Kg/cum

# How do you calculate the bulk density of pellets?

Mass divided by volume. Weigh the pellets to find the mass, then add the pellets to a measuring cylinder of water (or something of higher density than your pellets) and find t…he volume using the rise of water in the measuring cylinder

# What is the difference between bulk density and density?

It is the difference between the density of a bulk sample, and the density of a homogenous piece of the material being measured. The difference between the density o…f a pile of gravel, and one stone from the pile, for example. the pile is less dense. Or styrofoam peanuts versus polystyrene plastic, the same material in a different form. Used more in engineering, for things like earthfill, coal hauling, etc.

# Loose bulk density?

Bulk density is a major physical property in designing the logistic system for biomass handling. The size, shape, moisture content, individual particle density, and surface ch…aracteristics are few factors affecting the bulk density. This research investigates the effects of true particle lengths ranging from 6 to 50 mm and moisture contents ranging from 8% to 60% wet basis (wb) on the bulk density of wheat straw and switchgrass. Three types of particle densities of straw and switchgrass measured were: a hollow particle density assuming a hollow cylindrical geometry, a solid particle density assuming a solid cylindrical geometry, and a particle density measured using a gas pycnometer at a gas pressure of 40 kPa. The bulk density of both loose-fill and packed-fill biomass samples was examined. The calculated wet and dry bulk density ranged from 24 to 111 kg m-3 for straw and from 49 to 266 kg m-3 for switchgrass. The corresponding tapped bulk density ranged from 34 to 130 kg m-3 for straw and 68 to 323 kg m-3 for switchgrass. The increase in bulk density due to tapping the container was from 10% for short 6-mm particles to more than 50% for long 50-mm particles. An equation relating the bulk density of stems as a function of moisture content, dry bulk density, and particle size was developed. After the validation of this bulk density equation, the relationship would be highly useful in designing the logistics system for large-scale transport of biomass to a biorefinery. The bulk density and particle density data of uniform particles would be important, if straw and switchgrass is used for pulping and paper making.
