Density (volumetric mass density or specific mass) is a substance's mass per unit of volume. ... or geometrically from known dimensions. ...
(Mass) Density (or volume density) ρ: Mass per unit volume kg/m 3: L −3 M: intensive Mean lifetime: τ: Average time for a particle of a substance to decay s T: intensive Molar concentration: C: Amount of substance per unit volume mol⋅m −3: L −3 N: intensive Molar energy: J/mol: Amount of energy present in a system per unit amount of ...
density (L −3 M) = = = 5.1550 × 10 96 kg ... Physical quantities that have different dimensions (such as time and length) cannot be equated even if they are ...
If we distinguish between inertial mass with dimension and quantity of matter with dimension , then mass flow rate and density will use quantity of matter as the mass parameter, while the pressure gradient and coefficient of viscosity will use inertial mass. We now have four fundamental parameters, and one dimensionless constant, so that the ...
a is the scale factor, G, Λ, and c are universal constants (G is the Newtonian constant of gravitation, Λ is the cosmological constant with dimension length −2, and c is the speed of light in vacuum). ρ and p are the volumetric mass density (and not the volumetric energy density) and the pressure, respectively.
Quantity spatial density ρ = volume density (n = 3), σ = surface density (n = 2), λ = linear density (n = 1) No common symbol for n-space density, here ρ n is used. = Amount of property per unit n-space (length, area, volume or higher dimensions) [q]L −n: Specific quantity q m
The gamma (γ) a unit of magnetic flux density, corresponding to 1 nT. [14] The debye (D) is a unit of electric dipole moment equal to 10 −18 statC⋅cm, corresponding to ~ 3.335 64 qC⋅m. The buckingham (B) is a unit of electric quadrupole moment equal to 10 −26 statC⋅cm 2.
The specific weight, also known as the unit weight (symbol γ, the Greek letter gamma), is a volume-specific quantity defined as the weight W divided by the volume V of a material: = / Equivalently, it may also be formulated as the product of density, ρ, and gravity acceleration, g: = Its unit of measurement in the International System of Units (SI) is newton per cubic metre (N/m 3), with ...
