When modeling a tornado, one facetiously assumes two lines along which this equation does not hold, and it genuinely does not apply in reactor design. For an isochoric flow, this is reduced to the condition that the velocity field be solenoidal. The most general version of this equation states that 
When modeling a tornado, one facetiously assumes two lines along which this equation does not hold, and it genuinely does not apply in reactor design. For an isochoric flow, this is reduced to the condition that the velocity field be solenoidal. The most general version of this equation states that the partial derivative of density with respect to time at a point is equal to the divergence of the product of density and velocity at that point and its namesake property in velocity and density is all that is necessary to derive it. For ten points, name this fundamental equation of fluid flow, representing convervation of mass.

continuity equation (prompt on “conservation of mass” before it’s mentioned)
