Hydraulic Diameter

Hydraulic diameter, DH, is the characteristic length used to determine Reynolds number when dealing with flow in non-circular mediums. Reynolds number may then be of use in determining whether a…

Reflectivity

Reflectivity is the property by which an object is able to reflect light or radiation. Optically speaking, it refers to the amount of light that is reflected from incident light…

Material Hardness

There are different ways to define hardness depending on the material. For minerals, it is the property of resistance of a material to scratching by another material. Metallurgy defines hardness…

Graphene

The thinnest material known to man, graphene provides extreme strength, thermal conductivity, and electrical conductivity on par with copper. As such, this material has made an uproar with the scientific…
