Equation of Continuity

Equation of Continuity

### General Formula

$$\rho_1A_1v_1=\rho_2A_2v_2$$

### Terminologies

- ρ₁, ρ₂ → Fluid densities.

- A₁, A₂ → Cross-sectional areas.

- v₁, v₂ → Velocities.

### Conditions / Special Cases

For constant density:

$$A_1v_1=A_2v_2$$

### Usage

- Used in pipes and fluid flow calculations.
