Overview

The continuity equation expresses conservation of mass in fluid flow. For incompressible flow, the product of cross-sectional area and velocity is constant along a streamtube.

Variables

Symbol	Description	Unit
$A$	Cross-sectional area	m²
$v$	Flow velocity	m/s
$Q$	Volume flow rate	m³/s
$\dot{m}$	Mass flow rate	kg/s

Formula

$A_1 v_1 = A_2 v_2$
