WebMar 3, 2016 · Interpret a vector field as representing a fluid flow. The divergence is an operator, which takes in the vector-valued function defining this vector field, and outputs a scalar-valued function measuring the change in density of the fluid at each point. The formula for divergence is. div v ⃗ = ∇ ⋅ v ⃗ = ∂ v 1 ∂ x + ∂ v 2 ∂ y + ⋯. WebThis is the magnitude, 2.5 meters per second. And I'm also telling you the direction, to the right. So this is a vector quantity. This is a vector quantity. And when you specify both the speed and the direction, so the 2.5 meters per second is a scalar, and the direction, you are talking about velocity. You are talking about velocity.
