Apparatus and method to convey a fluid

Abstract

An apparatus includes a fluid path, a coupling, and a nozzle. The fluid path is to carry a fluid including one or more microparticles. The coupling is located in the fluid path. The nozzle is located in the fluid path to move the fluid through a stagnant region located near the coupling.
