I have been trying to fully understand this concept of Bernoulli's Principle , the Venturi effect and fluid velocity and energy. I need to grasp this to develop an idea that I have been working on.
1. As water is forced down a narrowing pipe, as the pipe gets more narrow, it means it losses more pressure and it's velocity increases. When it comes out of the narrow section (nozzle) it will have a higher velocity versus just a regular orifice (no narrowing). The higher velocity means a higher force or further distance traveled ?
2. The trade off of the higher force (velocity of water...assuming above is correct), is less flow, thus the conservation of energy principle is relevant here??
3. For a given static pressure of water in the pipe, we can aim for a higher force, or velocity by :
- making the final diameter more narrow
- creating a longer narrowing length (versus a short wide funnel) because this accelerates the water to faster speeds for a longer span
- smoother wall material
