Mass flux

In physics and engineering, mass flux is the rate of mass flow. Its SI units are kg m−2 s−1. The common symbols are j, J, q, Q, φ, or Φ (Greek lower or capital Phi), sometimes with subscript m to indicate mass is the flowing quantity. Mass flux can also refer to an alternate form of flux in Fick's law that includes the molecular mass, or in Darcy's law that includes the mass density. Sometimes the defining equation for mass flux in this article is used interchangeably with the defining equation in mass flow rate. For example, Fluid Mechanics, Schaum's et al uses the definition of mass flux as the equation in the mass flow rate article. (Wikipedia).

Gravitation (3 of 17) Mass vs Weight, An Explanation

Explains the difference between mass and weight. Very important. No they are not the same thing. Mass is a measure of the amount "stuff" something is made of, the amount of atoms for example. Weight is a measure of the force of attraction between two object that have mass. Of course mass

Volume Flow Rate & Mass Flow Rate - Fluid Dynamics Physics Problems

This physics video tutorial provides a basic introduction into mass flow rate and volume flow rate. The mass flow rate is the change in mass per unit time. It is also equal to the product of the fluid density, cross sectional area and the speed of the fluid in a pipe. The volume flow ra

What Is Mass?

Mass is a property which has been an axiomatic part of physics for centuries. Isn't it time we really figured out what is going on here? Shout out to Phil Matheson for creating the atmosphere where I could have an Aha! moment. Thanks to Alex Panin for introducing me to the idea of doppl

Flux Integrals | Lecture 42 | Vector Calculus for Engineers

A flux integral is the surface integral of a vector field. For examples, the mass flux is computed in fluid mechanics and the electric and magnetic fluxes are computed in electromagnetism. Both types of flux integrals are discussed in this video.

Gauss's Divergence Theorem

Gauss's Divergence theorem is one of the most powerful tools in all of mathematical physics. It is the primary building block of how we derive conservation laws from physics and translate them into partial differential equations. @eigensteve on Twitter eigensteve.com databookuw.com %%
