Calculate Water Loss in Broken Pipes: Formula/Equation

AI Thread Summary
To calculate water loss in broken pipes, Bernoulli's equation can be utilized as a starting point. A 63 mm PVC pipe typically carries between 50 to 150 gallons per minute, with common flow rates around 100 to 125 gpm. For practical measurement, timing how long it takes to fill a 5-gallon bucket can provide an empirical estimate of the leak rate. The actual flow may vary significantly based on specific conditions and pipe design. Accurate calculations require considering both theoretical equations and real-world measurements.

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.

Thread 'I need a concave mirror with a focal length length of 150 feet?'

I need to cut down a 3 year old dead tree from top down so tree causes no damage with small pieces falling. I need a mirror with a focal length of 150 ft. 12" diameter to 36" diameter will work good but I can't think of any easy way to build it. Nothing like this for sale on Ebay. I have a 30" Fresnel lens that I use to burn stumps it works great. Tree service wants $2000.

Thread 'Questions about the Tesla turbine'

Hi all, i have some questions about the tesla turbine: is a tesla turbine more efficient than a steam engine or a stirling engine ? about the discs of the tesla turbine warping because of the high speed rotations; does running the engine on a lower speed solve that or will the discs warp anyway after time ? what is the difference in efficiency between the tesla turbine running at high speed and running it at a lower speed ( as fast as possible but low enough to not warp de discs) and: i...

Thread 'Where is my curb stop?'

My water meter is submerged under water for about 95% of the year. Today I took a photograph of the inside of my water meter box because today is one of the rare days that my water meter is not submerged in water. Here is the photograph that I took of my water meter with the cover on: Here is a photograph I took of my water meter with the cover off: I edited the photograph to draw a red circle around a knob on my water meter. Is that knob that I drew a red circle around my meter...
