Calculate Water Loss in Broken Pipes: Formula/Equation

Click For Summary
SUMMARY

The discussion focuses on calculating water loss in broken pipes, specifically a 63mm PVC pipe. Bernoulli's equation serves as a foundational starting point for this calculation. It is noted that a 63mm pipe typically carries between 50 to 150 gallons per minute (gpm), with common flow rates around 100 to 125 gpm. An alternative method suggested is timing how long it takes to fill a 5-gallon bucket to estimate the leak rate.

PREREQUISITES
  • Understanding of Bernoulli's equation
  • Knowledge of flow rates in plumbing systems
  • Familiarity with measuring water flow in gallons per minute (gpm)
  • Basic principles of fluid dynamics
NEXT STEPS
  • Research advanced applications of Bernoulli's equation in fluid mechanics
  • Learn techniques for measuring flow rates accurately in plumbing
  • Explore methods for calculating water loss in various pipe sizes
  • Investigate tools for leak detection and monitoring in water systems
USEFUL FOR

Plumbers, civil engineers, environmental scientists, and anyone involved in water management and leak detection will benefit from this discussion.

Good day. Help me with a formula/equation to calculate water loss in broken pipes, e.g. a 63mm PVC pipe broken and spilling water.
 
Engineering news on Phys.org
Bernoulli's equation is a start.
 
I'm usually one to suggest formulas and theory and all that, but if it's still leaking can you just time how long it takes to fill up a 5 gallon bucket?

A 63 mm (2.5") pipe will generally carry somewhere in the range of 50-150 gpm in economic designs. Typically falling toward the middle of that range (100-125 gpm). Though of course there are many instances where flows are much higher or lower.
