jatkuvuusyhtälöksi
Jatkuvuusyhtälöksi is the Finnish term for the continuity equation. In physics and related fields, the continuity equation is a fundamental mathematical expression that describes the conservation of some quantity. This quantity could be mass, energy, electric charge, probability, or other conserved properties. The equation essentially states that the rate of change of the quantity within a given volume is equal to the net flux of that quantity into the volume.
Mathematically, the continuity equation is often expressed in differential form. For a quantity represented by a
In fluid dynamics, for instance, the continuity equation for an incompressible fluid simplifies to $\nabla \cdot
