Mass Flow Rate In physics and engineering, mass flow rate is the mass of a substance which passes 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 (ṁ, pronounced "m dot"), although sometimes μ (greek lowercase mu) is used. Learn what mass flow rate is, why it is important, and how to measure or calculate it using density and volume flow rate. see examples, formulas, and tables of common fluid properties.
