How do you calculate mass flux?

Mass flux is calculated by multiplying the density of the substance by its velocity and the cross-sectional area through which it flows. The formula is given by ( \text{Mass Flux} = \rho \cdot v \cdot A ), where ( \rho ) is the density (kg/m³), ( v ) is the velocity (m/s), and ( A ) is the area (m²). The result is expressed in units of mass per unit time, such as kg/s. This calculation is crucial in various applications, including fluid dynamics and engineering.
