To measure PEF, the detectors were changed to measure both gamma ray count rates for the density measurement and also the gamma ray energy levels for the PEF measurement. Most modern twodetector density devices use multiple energy windows to derive the density, the photoelectric factor, and the correction curve. In one threedetector wireline version, the combination of multiple detectors and ...

We can use the count rates measured in the higher energy shaded window (for hard gamma rays) as a measure of compton stering and hence the electron density of the material through which the gamma rays have passed. This gives information about the density of the formation in the same way as for the conventional formation density tool. The count rate of the soft gamma rays in the lower energy ...

Density is measured via energy attenuation of ionizing radiation. A radioactive source is contained in a leadfilled, steelencased housing is mounted on one side of a pipe with a scintillation detector mounted on the opposite side. Gamma energy emitted by the source passes through the pipe and the process material. As the density of the process material changes, the amount of energy reaching ...

The API measurement of density is reported a little differently. This measurement uses a comparison to water on an inverse scale. Water is represented by a 10 on the scale. Anything greater than 10 has a lower density than the water and will float upon it. Anything less than 10 will be heavier and sink in the water. Below is a chart displaying how API relates to specific gravity and weight per ...

Energy Density of Coal

Energy Density of Coal

The main use for coal is to produce energy but it can also be used to manufacture steel and is an important source of some of the chemicals used in pharmaceuticals, pesticides and fertilizers. Coal has a relatively high energy density of approximately 24 MJ/kg. Energy density can be defined as the amount of energy per mass. Its SI units are J/kg but MJ/kg is more common.

materials can have different densities and density can be used to identify a substance. Density (ρ)= Mass (M) Volume (V) Density is an intensive property, meaning it does not depend on the size of the object. A 1 mL sample of water, for example, has the same density as 1 gal of water. Mass and volume are extensive physical properties of matter, and vary with the size of the sample ...

A coalcutting machine is used in conventional mining to undercut, top cut, or shear the coal face so that coal can be fractured easily when blasted. It cuts 9 to 13 feet into the bed. Continuous auger machine is used in mining coalbeds less than 3 feet thick. The auger has a cutting depth of about 5 feet and is 20 to 28 inches in diameter ...

 · Relative coal density is measured as specific gravity. Specific gravity is the ratio of the mass of an object (solid or liquid) to the mass of an equal volume of water at 4°C. For reference, the specific gravity of water is 1. Materials with specific gravities of less than 1 float in water. Specific gravities that are greater than 1 sink in water. Because specific gravity is measured relative ...

 · Density is the measurement of the amount of mass per unit of volume. In order to calculate density, you need to know the mass and volume of the item. The formula for density is: density = mass/volume The mass is usually the easy part while finding volume can be tricky. Simple shaped objects are usually given in homework problems such as using a cube, or sphere. For a simple shape, use .
