Compressibility(C p): Compressibility is a calculation of a powder’s unit volume change after applying pressure. C p =100(ρ T −ρ B /ρ T) In this video, Shelly Zhang from Bettersize instrument teaches ...

It is tempting to think that some materials are always heavier than other materials. For example, someone might say that metal is heavier than air. But it depends on how much of each material there is ...

The theory of isoelectronic sequences of atoms has been developed as a perturbation theory and is extended here to the calculation of the first-order density matrix. It is shown that the calculation ...

Is there a plug and chug way to do it if I know my barometric pressure, temp, and altitude? I need to get it everyday before I have a flying lesson. I hate using that round slide-rule flight computer ...
