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:
“If mass communications blend together harmoniously, and often unnoticeably, art, politics, religion, and philosophy with commercials, they bring these realms of culture to their common denominator—the commodity form. The music of the soul is also the music of salesmanship. Exchange value, not truth value, counts.”
—Herbert Marcuse (1898–1979)
“Logic and fact keep interfering with the easy flow of conversation.”
—Mason Cooley (b. 1927)
“If you could choose your parents,... we would rather have a mother who felt a sense of guilt—at any rate who felt responsible, and felt that if things went wrong it was probably her fault—we’d rather have that than a mother who immediately turned to an outside thing to explain everything, and said it was due to the thunderstorm last night or some quite outside phenomenon and didn’t take responsibility for anything.”
—D.W. Winnicott (20th century)
