Hexadecimal (also known as base-16 or simply hex) is a positional numeral system that represents numbers using a radix (base) of sixteen. Unlike the decimal system representing numbers using ten symbols, hexadecimal uses sixteen distinct symbols, most often the symbols "0"–"9" to represent values 0 to 9 and "A"–"F" to represent values from ten to fifteen.
magnetostatics (ratio of the permeability of a specific medium to free space) Relative permittivity = electrostatics (ratio of capacitance of test capacitor with dielectric material versus vacuum) Specific gravity: SG (same as Relative density) Stefan number: Ste
In mathematics, the set of positive real numbers, > = {>}, is the subset of those real numbers that are greater than zero. The non-negative real numbers, = {}, also include zero.
The Nusselt number is the ratio of total heat transfer (convection + conduction) to conductive heat transfer across a boundary. The convection and conduction heat flows are parallel to each other and to the surface normal of the boundary surface, and are all perpendicular to the mean fluid flow in the simple case.
Free convection is caused by a change in density of a fluid due to a temperature change or gradient. Usually the density decreases due to an increase in temperature and causes the fluid to rise. This motion is caused by the buoyancy force. The major force that resists the motion is the viscous force. The Grashof number is a way to quantify the ...
The turbulent Schmidt number is commonly used in turbulence research and is defined as: [3] = where: is the eddy viscosity in units of (m 2 /s); is the eddy diffusivity (m 2 /s).; The turbulent Schmidt number describes the ratio between the rates of turbulent transport of momentum and the turbulent transport of mass (or any passive scalar).
Let be the free Abelian group of rank , whose elements are sequences of integers, and operation is the addition. A group order on Z n {\displaystyle \mathbb {Z} ^{n}} is a total order , which is compatible with addition, that is a < b if and only if a + c < b + c . {\displaystyle a<b\quad {\text{ if and only if }}\quad a+c<b+c.}
Wavenumber, as used in spectroscopy and most chemistry fields, is defined as the number of wavelengths per unit distance, typically centimeters (cm −1): ~ =, where λ is the wavelength.
