continuity equation
71Bernoulli's principle — This article is about Bernoulli s principle and Bernoulli s equation in fluid dynamics. For Bernoulli s Theorem (probability), see Law of large numbers. For an unrelated topic in ordinary differential equations, see Bernoulli differential… …
72Incompressible flow — In fluid mechanics or more generally continuum mechanics, an incompressible flow is solid or fluid flow in which the divergence of velocity is zero. This is more precisely termed isochoric flow. It is an idealization used to simplify analysis. In …
73Charge density — The linear, surface, or volume charge density is the amount of electric charge in a line, surface, or volume, respectively. It is measured in coulombs per meter (C/m), square meter (C/m²), or cubic meter (C/m³), respectively, and represented by… …
74Betz' law — Please see discussion accessed from the above tab for issues related to proof. Betz law reflects a theory for flow machines, developed by Albert Betz. It shows the maximum possible energy known as the Betz limit that may be derived by means of an …
75Boussinesq approximation (water waves) — In fluid dynamics, the Boussinesq approximation for water waves is an approximation valid for weakly non linear and fairly long waves. The approximation is named after Joseph Boussinesq, who first derived them in response to the observation by… …
76Dissipative soliton — Dissipative solitons (DSs) are stable solitary localized structures that arise in nonlinear spatially extended dissipative systems due to mechanisms of self organization. They can be considered as an extension of the classical soliton concept in… …
77Orifice plate — Flat plate, sharp edge orifice ISO 5167 Orifice Plate An orifice plate is a device used for measuring the volumetric flow rate. It …
78Mass balance — A mass balance (also called a material balance) is an application of conservation of mass to the analysis of physical systems. By accounting for material entering and leaving a system, mass flows can be identified which might have been unknown,… …
79Chemical transport model — A chemical transport model (CTM) is a type of computer numerical model which typically simulates atmospheric chemistry. Contents 1 Chemical transport models and general circulation models 2 Types of chemical transport models 2.1 Methodologies …
80Dynamic similarity (Reynolds and Womersley numbers) — Contents 1 Derivation 2 Dynamic similarity use 3 Boundary layer thickness 4 References 5 Exter …
