mass-energy equation
91Convection–diffusion equation — The convection–diffusion equation is a parabolic partial differential equation combining the diffusion equation and the advection equation, which describes physical phenomena where particles or energy (or other physical quantities) are… …
92Compressed air energy storage — Conceptual representation of the compressed air energy storage concept. Off peak (low cost) electrical power compresses air into an underground air storage “vessel” (the Norton mine), and later the air feeds a gas fired turbine generator complex… …
93Muzzle energy — is the kinetic energy of a bullet as it is expelled from the muzzle of a firearm. It is often used as a rough indication of the destructive potential of a given firearm or load. The heavier the bullet and the faster it moves, the higher its… …
94Proton transfer reaction - mass spectrometry — (PTR MS) is a very sensitive technique for online monitoring of volatile organic compounds (VOCs) in ambient air developed by scientists at the Institut für Ionenphysik at the Leopold Franzens University in Innsbruck, Austria [A. Hansel, A.… …
95Constitutive equation — Many defining equations are in the form of a constitutive equation, since parameters of a property or effect associated matter are characteristic to the substance in question. A large number of other defining equations not specifically… …
96Pauli equation — The Pauli Equation, also known as the Schrödinger Pauli equation, is the formulation of the Schrödinger equation for spin one half particles which takes into account the interaction of the particle s spin with the electromagnetic field. It is the …
97Fermi energy — The Fermi energy is a concept in quantum mechanics usually referring to the energy of the highest occupied quantum state in a system of fermions at absolute zero temperature. This article requires a basic knowledge of quantum mechanics.Note that… …
98Sackur–Tetrode equation — The Sackur–Tetrode equation is an expression for the entropy of a monatomicclassical ideal gas which uses quantum considerations to arriveat an exact formula. Classical thermodynamics can only give the entropy of a classical ideal gas to within a …
99Mason equation — The Mason equation is an approximate analytical expression for the growth (due to condensation) or evaporation of a water droplet it is due to the meteorologist B. J. Mason.[1] The expression is found by recognising that mass diffusion towards… …
100Saha ionization equation — The Saha ionization equation, also known as the Saha Langmuir equation, was developed by the Indian astrophysicist Megh Nad Saha in 1920, and later (1923) by Irving Langmuir. One of the important applications of the equation was in explaining the …
