Power Density Primer: Understanding the Spatial Dimension ,

gravimetric density of energy converters: when evaluating batteries (whose mass and volume we usually try to minimize) power density refers to the rate of energy release per unit of battery volume or weight (typically W/dm3 or W/kg); similarly, in nuclear engineering power density is the rate of energy release per unit volume of a reactor core...

Acoustic properties of coal from lab measurement

reveals that the coal formation is frequently associated with the generation of other hydrocarbon resources (Diessel, 1992) It can be the source rock for gas and oil, which implies the possible proximity of coal formation to oil or gas reservoirs The special acoustic properties of the coal formation, eg, low velocity and low density, cause ....
