Abstract
The exit tip length of a liquid jet nozzle is the main parameter that governs the jet flow characteristics. And in this study, some flow characteristics with the variation of nozzle exit tip length such as mean pressure distributions, velocity distributions, energy and momentum variations along the centerline, have been experimentally investigated. Through the experimental analyses, the longer exit tip length was found to decrease the jet kinetic energy because of the friction losses passing through the nozzle tip. As the results, the available semi-empirical equations for momentum and kinetic energy deficit could be derived.
