Mass Flow Rate

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

mass flow rate 1Mass 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.

\(\large{ \dot m_f = \rho \; v \; A   }\)         

Where:

\(\large{ \dot m_f }\) = mass flow rate

\(\large{ A }\) = area of cross section

\(\large{ \rho }\)  (Greek symbol rho) = fluid density

\(\large{ v }\) = fluid velocity
