Channels A through H are indicated in many European TVs as Channels 13–20. Channels B, C, D, H, H1, and H2 are identical to Channels E4, E4A, E5, E10, E11, and E12. Channel A video carrier is the same as Channel E2 audio carrier and thus it used to be common that the audio from a distant TV station on channel E2 received via Sporadic E ...
v. t. e. In physics and engineering, in particular fluid dynamics, the volumetric flow rate (also known as volume flow rate, or volume velocity) is the volume of fluid which passes per unit time; usually it is represented by the symbol Q (sometimes ). It contrasts with mass flow rate, which is the other main type of fluid flow rate.
Harvard's T.H. Chan School of Public Health traces its origins to the Harvard- MIT School for Health Officers, which was founded in 1913. Harvard calls it "the nation's first graduate training program in public health." In 1922, the School for Health Officers became the Harvard School of Public Health. In 1946, it was split off from Harvard ...
A function f of x, differentiated once in Lagrange's notation. One of the most common modern notations for differentiation is named after Joseph Louis Lagrange, even though it was actually invented by Euler and just popularized by the former. In Lagrange's notation, a prime mark denotes a derivative.

Here, U is internal energy, T is absolute temperature, S is entropy, P is pressure, and V is volume. This is only one expression of the fundamental thermodynamic relation. It may be expressed in other ways, using different variables (e.g. using thermodynamic potentials). For example, the fundamental relation may be expressed in terms of the ...
Dimension. In physics and engineering, mass flow rate is the mass of a substance which passes per unit of time. Its unit is kilogram per second in SI units, and slug per second or pound per second in US customary units. The common symbol is ( ṁ, pronounced "m-dot"), although sometimes μ ( Greek lowercase mu) is used.
Equations. Maxwell–Boltzmann distribution. v = velocity of atom/molecule, m = mass of each molecule (all molecules are identical in kinetic theory), γ ( p) = Lorentz factor as function of momentum (see below) Ratio of thermal to rest mass-energy of each molecule: θ = k B T / m c 2 {\displaystyle \theta =k_ {B}T/mc^ {2}\,\!}
