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.
