# Mass Flow Rate

Mass flow rate, abbreviated as \(\dot m_f\), is the average velocity of a mass that passes by a point. In engineering, mass flow rate is often used, along with the conservation of mass to determine how much product moves through a pipe or duct. The calculation and formula for determining the mass flow rate where the flow area and density are known.

## Mass flow rate Formula\(\large{ \dot m_f = \rho \; v \; A_c }\) Where: \(\large{ \dot m_f }\) = mass flow rate \(\large{ A_c }\) = area cross-section \(\large{ \rho }\) (Greek symbol rho) = density of fluid \(\large{ v }\) = velocity of fluid |
