Optimal Copper Pipe Size for Misting System

Click For Summary
SUMMARY

The discussion focuses on determining the optimal copper pipe size for a misting system connected to a 5/8" garden hose operating at approximately 70psi. Users are considering using either 3/4" or 1/2" copper pipes to ensure consistent pressure at each mist nozzle. Key factors influencing pressure drop include water flow rates, which need to be quantified based on the expected output from the nozzles. A flow rate of a pint per minute may be acceptable, while a gallon per minute could lead to inconsistencies.

PREREQUISITES
  • Understanding of fluid dynamics and pressure drop calculations
  • Familiarity with misting system components and configurations
  • Knowledge of copper pipe sizing standards
  • Experience with water flow measurement techniques
NEXT STEPS
  • Research "Pressure drop calculations for copper piping" to understand how pipe diameter affects flow
  • Learn about "Misting system design principles" to optimize nozzle placement and water distribution
  • Investigate "Flow rate measurement techniques" to accurately assess water output from nozzles
  • Explore "Hydraulic calculations for irrigation systems" to apply principles to misting setups
USEFUL FOR

Landscape architects, irrigation specialists, and DIY enthusiasts designing misting systems who need to ensure consistent water pressure across multiple nozzles.

TL;DR
Figuring for pressure change due to an increase or decrease in pipe size
I am attaching a standard 5/8" garden hose with approximately 70psi pressure to a copper pipe that is capped on the opposite end with mist nozzles mounted periodically along its length. I want the pressure at each mister to be as similar as possible. The hose attaches at the base, a solid line goes 8 feet vertically and then the misters are mounted on a horizontal portion. For my copper lines I have 3/4" copper and 1/2" copper and I am wondering which I should use to have consistency after coming out of the 5/8" hose and into the misting system.

Hi @ljmorlock
Pressure drop for the pipes ( and the garden hose ) will be a factor of the amount of water flow, a factor that you need to quantify by the amount of water ( expected ) to come out of the nozzles.
A pint a minute might be OK, a gallon a minute might not.
