Thermal length Thermal length (Θ) is the relationship between temperature difference δt on one side and LMTD. Θ = Thermal length describes how difficult a duty is from a thermal perspective. Density Density(ρ) is the mass per unit volume

www.energy.govthe theory of atomic structure. In 1904 he wrote: If it were ever possible to control at will the rate of disintegration of the radio elements, an enormous amount of energy could be obtained from a small amount of matter. Albert Einstein developed his theory of the relationship between mass and energy one year later. The mathematical formula is ...
The Physics of Nuclear Weapons - Stanford EE
ee.stanford.eduThe above discussion points out that what is usually called critical mass is really a critical mass density. After a bomb based on U-235 explodes, most of the U-235 is still present. It is just too thinly dispersed to maintain a chain reaction. Too few neutrons are captured by other U-235 atoms to maintain the chain reaction.

www.cdc.gov1994). To be effective and efficient, the cardiovascu-lar system should be able to respond to increased skeletal muscle activity. Low rates of work, such as walking at 4 kilometers per hour (2.5 miles per hour), place relatively small demands on the cardio-vascular and respiratory systems. However, as the rate of muscular work increases, these ...
