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.

Mass Flow Rate formula

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

Where:

 Units English Metric
\(\large{ \dot m_f }\) = mass flow rate \(\large{\frac{lbm}{sec}}\) \(\large{\frac{kg}{s}}\)
\(\large{ A_c }\) = area cross-section \(\large{ft^2}\) \(\large{m^2}\)
\(\large{ \rho }\)  (Greek symbol rho) = density \(\large{\frac{lbm}{ft^3}}\) \(\large{\frac{kg}{m^3}}\)
\(\large{ v }\) = velocity \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
