Can you make laminar flow?
To generate laminar flow we’re going to create a nozzle that makes the water flow in smooth layers. Slow water is more likely to be laminar, so first we need to slow the water down. Second We also need to remove turbulence from the water coming into the nozzle. And third we have to direct the water into a laminar flow.
