In various scientific and engineering fields, calculating volume with density and mass is a crucial skill. It plays a significant role in understanding the physical properties of different substances ...

Before we delve into calculations, let’s define each term: 1. Mass: Mass is a measure of the amount of matter present in an object. It is typically expressed in units of grams (g) or kilograms (kg). 2 ...

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 ...

Abstract: To improve the volume power density of proton exchange membrane fuel cell (PEMFC), a design of graphite bipolar plate straight channel characterized by narrow ribs is studied in this article ...
