When a fluid is in motion, it must move in such a way that mass is conserved. Continuity equation states that A1V1=A2V2. Stokes’s law, mathematical equation that expresses the settling velocities of small spherical particles in a fluid medium. It is used to measure the viscosity of the given liquid.
In fluid dynamics , the continuity equation states that the rate at which enters mass enters a system is equal to the rate at which mass leaves the system plus the accumulation of mass within the system .
The relationship between equation of continuity and Stokes law is that both take into account the velocity of viscous fluid but they are entirely two different law . Stokes law gives the expression for the force of viscosity acting on a small sphere moving through a viscous fluid . Continuity equation states that a1v1=a2v2 .
