In physics and engineering, mass flow rate is the mass of a substance which passes through a given surface per unit of time. Its unit is kilogram per second in SI units, and slug per second or pound per second in US customary units. The common symbol is (pronounced "m-dot"), although sometimes μ (Greek lowercase mu) is used.
Sometimes, mass flow rate is termed mass flux or mass current, see for example Fluid Mechanics, Schaum's et al. In this article, the (more intuitive) definition is used.

Famous quotes containing the words mass, flow and/or rate:
“A serious problem in America is the gap between academe and the mass media, which is our culture. Professors of humanities, with all their leftist fantasies, have little direct knowledge of American life and no impact whatever on public policy.”
—Camille Paglia (b. 1947)
