Velocity derivative calculation on the boundary

Guys,

I want to calculate a value which is a known derivative of a function and then give it as a Dirichlet boundary condition on the outflow.

So i want to calculate the function K that is equal to the derivative of the velocity times the normal vector. Note that the velocity is taken from the previous timestep so it is a known function. Also we know the normal vector. After I get all the different values along the boundary I want to impose them as DirichletBC.

Any ideas?
