How much does the shaping of the short turn increase flow?Quite a bit. These heads are very small over the short turn so the speeds are very high. If the short turn is wrong this head will plateau off at .450" and the swirl will go through the roof. So look at the flow sheet at .450 and draw a straight line to .600 and that is what the flow will be. The swirl will jump about a 1000RPM so low 3000's. When the short side is poor the flow zone shuts down and creates a nozzle.
