Calculate Water Loss in Broken Pipes: Formula/Equation

In summary, the conversation discusses using Bernoulli's equation to calculate water loss in a broken pipe and suggests timing how long it takes to fill a 5 gallon bucket as an alternative method. The estimated flow rate for a 63 mm PVC pipe is 50-150 gpm.

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.

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.

FAQ: Calculate Water Loss in Broken Pipes: Formula/Equation

How do you calculate water loss in broken pipes?

The formula for calculating water loss in broken pipes is: Water Loss = Pipe Burst Area x Pipe Pressure x Time.

What is the Pipe Burst Area?

The Pipe Burst Area refers to the size of the hole or break in the pipe where the water is escaping.

How do you determine the Pipe Pressure?

The Pipe Pressure can be measured using a pressure gauge, or it can be estimated based on the water pressure in the area and the size and type of the pipe.

What units should be used in the formula?

The units for Water Loss are typically in liters or gallons, Pipe Burst Area is in square meters or feet, and Pipe Pressure is in pounds per square inch (psi) or kilopascals (kPa).

How can calculating water loss in broken pipes be helpful?

Calculating water loss in broken pipes can help identify the extent of the damage and the amount of water that needs to be repaired or replaced. This information can also be used to estimate the cost of repairs and to inform water conservation efforts.
