In fluid dynamics, the mass of the fluid flowing through a specific cross-section can be calculated using the following equation: where: t is the time during which the fluid moves, with SI units of s. v is the velocity with which the fluid moves, with SI units of m/s. A is the cross-sectional area of the system, with SI units of m 2.

Formulation and examples. The law of conservation of mass can only be formulated in classical mechanics, in which the energy scales associated with an isolated system are much smaller than, where is the mass of a typical object in the system, measured in the frame of reference where the object is at rest, and is the speed of light.. The law can be …

Fluid Flow: Conservation of Momentum, Mass, and Energy

The equations for the conservation of momentum, mass, and energy can also be used for fluid flow that involves multiple phases; for example, a gas and a liquid phase or two different liquid phases, such as oil and water. The most detailed way of modeling multiphase flow is with surface tracking methods, such as the level set or phase …

Principle of Conservation of Mass

Mass conservation for closed systems continues to be true exactly. The mass-energy equivalence theorem states that mass conservation is equivalent to energy conservation, which is the first law of thermodynamics. The mass-energy equivalence formula requires closed systems, since if energy is allowed to escape a system, mass will escape also. ...
