121Mie–Gruneisen equation of state — The Mie Gruneisen equation of state is a relation between the pressure and the volume of a solid at a given temperature. It is often used to determine the pressure in a shock compressed solid. Several variations of the Mie Gruneisen equation of… …
122Hagen-Poiseuille equation — The Hagen Poiseuille equation is a physical law that describes slow viscous incompressible flow through a constant circular cross section. It is also known as the Hagen Poiseuille law, Poiseuille law and Poiseuille equation.Equationtandard fluid… …
123Convection–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… …
124Morison equation — Flow forces according to the Morison equation for a body placed in a harmonic flow, as a function of time. Blue line: drag force; red line: inertia force; black line: total force according to the Morison equation. Note that the inertia force is… …
125Dirichlet's energy — In mathematics, the Dirichlet s energy is a numerical measure of how variable a function is. More abstractly, it is a quadratic functional on the Sobolev space H1. The Dirichlet energy is intimately connected to Laplace s equation and is named… …
126Mason 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… …
127Tolman-Oppenheimer-Volkoff equation — In astrophysics, the Tolman Oppenheimer Volkoff (TOV) equation constrains the structure of a spherically symmetric body of isotropic material which is in static gravitational equilibrium, as modelled by general relativity. The equation… …
128Integral equation — In mathematics, an integral equation is an equation in which an unknown function appears under an integral sign. There is a close connection between differential and integral equations, and some problems may be formulated either way. See, for… …
