"WebThe enstrophy (density) is defined as Ω ≡ ω 2 / 2 and the kinetic energy (density) is k ≡ u 2 / 2. We consider a general stationary curved wall ∂ B with the no-slip velocity boundary condition (namely, u ∂ B = 0). The unit normal vector of the boundary surface is denoted by n, directing from the wall to the fluid. " - Is density a scalar

WebDensity is scalar. I think you are picking up the confusion from “density distribution”. A given object can have variable density i.e. different density at different points. But it doesn’t make density a vector quantity itself, it is the material’s property. Brian Bi majored in physics Upvoted by Quora User WebA scalar quantity can be described fully by stating its magnitude (size).
