Continuity Equation for Mass

This formula states that the mass entering a system is equal to the mass leaves the system both at the same rate.

 

Continuity Equation for Mass formula
\( A_1 \; v_1 = A_2 \; v_2  \)
Symbol	English	Metric
\( A_2 \) = final area cross-section	\(in^2\)	\(mm^2\)
\( A_1 \) = initial area cross-section	\(in^2\)	\(mm^2\)
\( v_2 \) = final cross-section velocity	\(ft\;/\;sec\)	\(m\;/\;s\)
\( v_1 \) = initial cross-section velocity	\(ft\;/\;sec\)	\(m\;/\;s\)
