continuity equation 1

This formula calculates the initial density of the fluid.

 

Continuity Equation for Density formula

\(\large{ \rho_1 = \frac{ \rho_2 \; A_2 \; v_2 }{ A_1 \; v_1 }  }\)   

Where:

\(\large{ \rho_1 }\)  (Greek symbol rho) =  initial cross-section densityden

\(\large{ A_2 }\) = final area cross-section

\(\large{ A_1 }\) = initial area cross-section

\(\large{ \rho_2 }\)  (Greek symbol rho) =  final cross-section density

\(\large{ v_2 }\) = final cross-section velocity

\(\large{ v_1 }\) = initial cross-section velocity
