Water stream projection distance calculation for different nozzle shapes

Click For Summary
SUMMARY

The discussion focuses on calculating the projection distance of water streams from various nozzle shapes, specifically when using a 120 PSI diaphragm pump with 6mm tubes and 0.4mm misting nozzles. The user seeks guidance on the relevant equations for determining the distance water can travel when nozzles are directed horizontally or at a 45-degree angle. Key considerations include the effects of gravity and nozzle angle on the distance before drift occurs. The conversation highlights the need for theoretical understanding and practical application of spray coverage formulas and water jet dynamics.

PREREQUISITES
  • Understanding of fluid dynamics principles
  • Familiarity with spray coverage formulas
  • Knowledge of water jet projection equations
  • Basic grasp of atmospheric conditions affecting fluid behavior
NEXT STEPS
  • Research the equations for horizontal and angled water jet projection

  • Explore spray coverage calculations for different nozzle shapes
  • Investigate empirical data on water stream distances from various nozzle configurations
USEFUL FOR

This discussion is beneficial for engineers, hobbyists, and researchers involved in fluid dynamics, nozzle design, and spray technology, particularly those seeking to optimize water projection systems.

Hello,
I have built a device and i want to test different types of nozzles. Problem is; the size of the nozzles i need are hard to find in company stock. So i need to make sure before i make any order.

I have no background or degree any related area so it is hard to understand the equations, how to use them in my case.
I have checked all the formulas about nozzle distance but in most examples the nozzle are directed to the ground.

If someone have spare time, please guide me about the formula for distance that nozzles can shoot water before drift when directed horizontally or upwards with a 45 degree angle like in the pic attached.

I am using a 120 PSI diaphragm pump, 6mm tubes and 0.4mm misting nozzle. What is the effect of the gravity and nozzle angle in this case?

Thank you.

Please tell us more details about the equations you've seen, and what you have tried so far.
 
I imagine the OP has looked for information in Firefighting sources? I would imagine that tables obtained from measurements would be more available than equations.

Hello, i am working on the spray coverage formula and trying to find a connection with the water jet formula. I need to find the "L" before drift in different positionings of the nozzle. Atmospheric conditions but no wind. I guess it will be theoretical.
Thank you.

@sophiecentaur now i will check those too, Thank you.
