Tangential Entery Nozzle

The answer is in the question. A tangential nozzle is at 0deg by definition, i.e. at a tangent to the vessel wall. If it were at any other angle, it wouldn't be a tangential nozzle!

The purpose of it is to set up some swirl in the vessel. As the incoming fluid is forced into a spiral motion, the acceleration set up within the spiral effects a separation based upon the differences in densities of the immiscible components within the incoming fluid stream. In this way, tangential separation can be achieved in a smaller volume, and therefore at smaller capital cost and space requirements, than using gravity separation in, say, a settlement pond, the room for which may not be available in an oil storage facility - after all, the facility is there to store oil, not an oil/water mix.
