However, in some texts, I see the solutions using the gradient vector instead? The surface integral of f over Σ is. ∬ Σ f ⋅ dσ = ∬ Σ f ⋅ ndσ, where, at any point on Σ, n is the outward unit normal vector to Σ. Note in the above definition that the dot product inside the integral on the right is a real-valued function, and hence we can use Definition 4.3 to evaluate the integral. Example 4.4.1.The flow rate of the fluid across S is ∬ S v · d S. ∬ S v · d S. Before calculating this flux integral, let’s discuss what the value of the integral should be. Based on Figure 6.90, we see that if we place this cube in the fluid (as long as the cube doesn’t encompass the origin), then the rate of fluid entering the cube is the same as the rate of fluid exiting the cube.

The whole point here is to give you the intuition of what a surface integral is all about. So we can write that d sigma is equal to the cross product of the orange vector and the white vector. The orange vector is this, but we could also write it like this. This was the result from the last video.
