mx5,
Whatever water is left after the injection will be drawned out by any partial vacuum caused by fast mioving air travelling pass the top of the jet, similar to a spraying perfume.
The only way to stop the jet dripping is to have "zero cavity" at the point of delivery.
If the hose is 250mm long, the amount of water drip will be:
Lx (0.5x ID)^2 x PI = 1.227 ml (hose ID=2.5mm)
