In powder compaction process, there are two criteria which define the boundary of elastic-plastic limits, notably, shear and hydrostatic.However, the physical behavior after the stress state reaches the yield point will be different for these criteria. In die powder compaction, the material undergoes continuous yielding (i.e. decrease in volume) until it reaches a state where particle …

[08:13] Where to Find Emission Factors. How to determine an emission factor is one of the most common questions in calculating an equipment's emissions. We have an entire video that describes the four ways to determine an emission factor (listed here in order from most accurate to least): Do a direct measurement, or source test.

An emissions factor is a representative value that attempts to relate the quantity of a pollutant released to the atmosphere with an activity associated with the release of that pollutant. These factors are usually expressed as the weight of pollutant divided by a unit weight, volume, distance, or duration of the activity emitting the pollutant ...
