Calculate fluid pressure loss due to hole leakage

AI Thread Summary
In a cylindrical pipe with a 5mm internal diameter and capped at one end, the pressure loss due to fluid leaking from side holes can be influenced by the source of the fluid. If the fluid is supplied from a constant-head tank, pressure remains stable despite the leaks. However, if the tank is not being refilled, pressure loss will occur as the water level drops, with the rate of loss depending on the tank's horizontal area. The discussion highlights the importance of the fluid source in determining pressure dynamics. Understanding these factors is crucial for accurately calculating pressure loss in such scenarios.

I have a cylindrical pipe of internal diameter of around 5mm, say capped at one end with pressurised fluid flowing though the other opening. If I have holes at the wall of the pipe, am i able to calculate the pressure loss due to water squirting out through those side holes?

hi raymond350! welcome to pf! :smile:

if it's capped at the end, why should there be any pressure loss?

if the water supply is from a constant-head tank, then the pressure will stay the same

if it's from a tank that isn't being refilled, then the loss of pressure will depend on the horizontal area of the tank … the faster the water goes down, the greater the loss in pressure :wink:

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
