continuity equation mass 1

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

\(\large{ A_1 \; v_1 = A_2 \; v_2  }\)   

Where:

 Units English Metric
\(\large{ A_2 }\) = final area cross-section \(\large{in^2}\) \(\large{mm^2}\)
\(\large{ A_1 }\) = initial area cross-section \(\large{in^2}\) \(\large{mm^2}\)
\(\large{ v_2 }\) = final cross-section velocity \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
\(\large{ v_1 }\) = initial cross-section velocity \(\large{\frac{ft}{sec}}\) \(\large{\frac{m}{s}}\)
