What is the equation used to express mass balance in this context?

$\rho_1A_1v_1 = \rho_2A_2(v_1 - v_3) + \rho_3A_3v_3$

$\rho_1A_1v_1 = \rho_2A_2v_2 + \rho_3A_3v_3$ (correct)

$\rho_2A_2v_2 = \rho_1(A_1v_1 - A_3v_3) + \rho_3A_3v_3$

$\rho_1A_1v_1 = \rho_2(A_1v_1 - A_3v_3) + \rho_3A_3v_3$

Based on the information provided, what does the expression $A_1v_1(\rho_1 - \rho_2) = A_3v_3(\rho_3 - \rho_2)$ represent?

Mass conservation equation

Density balance equation (correct)

Energy balance equation
